Birthday looks like any other 4th of july so far. There are parades in towns and cities across the country; watermelon eating contests like this one in davie, florida; and celebrations of the nations liberty. But the signs are also plain to see that this 4th is marked by heightened concern about a possible terror attack. While the Intelligence Community has not pointed to any specific credible threats, the many gatherings on this holiday packed with National Symbolism have police on high alert. Heres David Begnaud. Reporter in new york city tonight, Law Enforcement is sending out a united message if you dare to do harm, were ready for you. We need to be here tonight. Reporter n. Y. P. D. Commissioner bill bratton says the department is worried about lone wolf attacks. Well, we have. We have increasing concerns, as you are aware, over the last several months, of the inspired threat that isis is constantly trying to encourage. So, its not so much what we know that concerns us but what we might not know. Reporter canines and heavily armed officers are visible with many more under cover, some with devices that can detect dirty bombs. The n. Y. P. D. Is also monitoring thousands of security cameras. Steve jazinsky from australia says the threats are not a deterrent. You cant let warnings like that stop from you doing. Living your life. Youve got to keep living. If you stop seeing things like the fireworks tonight, then the terrorists have won. So, we think you just got to keep doing it. Reporter in washington d. C. , 18,000 feet of chain link fence surrounds the national mall. Some 700,000 people will be screened before they can find a spot to watch the fireworks. In chicago, Police Officers are working 12hour shifts to guard a concert, baseball games and fireworks. Sean henry is a former executive assistant director at the f. B. I. And the f. B. I. And local Law Enforcement do not have the resources to keep these people under 24hour surveillance. So, essentially, what you have is this tinder box, a perfect storm, if you will, where theres this great concern because we know the threats there, there are people who have an interest in harming americans, but theres not all the resources to keep them in check. Reporter the n. Y. P. D. Police commissioner says the 7,000 Police Personnel on duty will remain on duty throughout the weekend. Jim . Axelrod David Begnaud in lower manhattan. David, thank you. In droughtstricken california firefighters are also on high alert tonight. Fireworks last year sparked 300 fires. Carter evans looks at the bigger concern this year. cheers and applause reporter the spectacular professional fireworks shows are not what concerns Southern California firefighters; its this illegal fireworks launched from backyards. Theyre prevalent and worrisome to Orange County fire captain steve hurdle. Its really the biggest day of the year for firefighters. Its when were most on our guard. Reporter when you look at this brush, how quickly could Something Like this light on fire . Instantaneously. The aerials that go up and fall out, theyre still hot. They still have that hot ember and who knows where they will land . They could land anywhere in any type or form of brush. Reporter that danger has caused several cities in the west to impose emergency bans on fireworks after recent wildfires destroyed dozens of homes. But in the city of anaheim, so called safe and sane fireworks that dont launch into the air but still could spark a wildfire are now legal for the first time in three decades. Have you seen how dry all the brush is around here . Yes, its terrible. Reporter jesus isres is planning to light his fireworks in a parking lot. You dont want to be the guy that starts a fire. You want to be the guy that has fun reporter susan rogers also plans to keep it safe. Does it concern you that other people might not be so safe . Sure, theres always people that are going to break the laws and act like idiots, but you hope for the best. Reporter so are firefighters, who can hardly wait for the 5th of july. Carter evans, cbs news, los angeles. Axelrod the fireworks got off to an early and dangerous start outside denver.

Surprisingly, no one was seriously hurt. With its banks set to run out of money on monday, greece is just hours away from a crucial vote about its financial future. Holly williams is in athens tonight. Reporter the banks are closed and withdrawals at cash machines are limited to just under 60 a day. As greece stares bankruptcy in the face, its people will vote tomorrow in a referendum. The answer is a simple yes or no. The problem is that greeks cant agree what the question is. The government here says its asking greeks whether to accept the terms demanded by foreign creditors in return for an extended financial bailout. Those terms include steep tax hikes, slashing pensions and public spending cuts. Greeces radical left wing prime minister, alexis tsipras, has urged his people to vote no. He broke off talks with the creditors last week, saying their strict conditions amount to blackmail. But greeces International Creditors say their offer has now expired. If greeks vote no, the country could be forced to leave the single european currency and start printing its own money. Greece has already been bailed out twice in the last five years, with loans of over 250 billion. But its economy has never recovered from the financial crisis of 2008 and unemployment is now at over 25 . At this rally for those who plan to vote yes, many believe that leaving the euro would turn a bad situation into a catastrophe. Im here because im european, said ioannis tziveris. Where else am i supposed to go . The polls show that greeks are divided right down the middle on the referendum, with around 10 still undecided. Greece is a tiny country of just 11 million people, jim, but if it does leave the single european currency, that would trigger financial losses around the world. Axelrod Holly Williams covering for us tonight in athens. Holly, thank you very much. There are strong signs tonight of a breakthrough in the Nuclear Negotiations with iran over one of the most contested issues sanctions. Margaret brennan is traveling with secretary of state john kerry in vienna, austria. Margaret, when we say strong signs of a breakthrough, what do we mean . Reporter well, jim, exactly when iran will get sanctions relief has been really one of the thorniest issues, and theres now a proposed compromise. Here is how it would work. Instead of giving in to irans demand for an immediate suspension of sanctions, that will instead happen over three stages. So, as iran starts to freeze its nuclear program, the u. S. And western powers will then peel back a set of the restrictions. But none of this is going to happen as quickly as the iranians had hope. Axelrod so, does this mean we are in any way close to a final deal . Reporter it looks like it. Irans top negotiator, javad zarif, issued an 11thhour video appeal and said the two sides have never been closer, but then he also said the u. S. Needs to stop making demands. And thats likely a reference to the american stipulation that inspectors get access to all suspected sites, including military installations. But one iranian top diplomat told me that if the americans are willing to compromise on this, it could open the way for the u. S. And iran to Work Together on common threats including the fight against isis. Axelrod Margaret Brennan covering for us tonight in vienna. Margaret, thank you. The u. S. Womens soccer team will play for the world cup tomorrow in vancouver, meeting japan in the final. Now, win or lose, itll be the last world cup game for the National Teams alltime goal scoring leader. But as Jericka Duncan reports, Abby Wambachs teammates plan to make it a win. cheers and applause reporter no one in the world, male or female, has scored more International Goals than abby wambach. But of the 183 goals, there is one that pretty much defines her the 2011 world cup, america down a goal to brazil and literally seconds away from an embarrassingly early exit. What a moment in time, an iconic moment to be part of. There were so many things that needed to be perfect for that brazil goal. Some people thought we won the world cup in that game. The world cup to japan reporter but they didnt eventually losing in the final to japan, a loss that has fueled wambachs obsession to finally put a world cup title on her otherwise impeccable resume. cheers and applause have you had any visions about how this will end . If there was any year for us to win, this has to be the one right . Its the end for me when it comes to talking about world cups. And for me, i like storybook endings, as well. Reporter wambach, now 35 has been mostly a sub in this tournament, giving way to younger and faster players. But rather than fuss and fume, shes embraced the role of mentor and motivator; shell get right in her teammates faces when needed. Abbys a true leader. You know, when she has something to say, everyone listens. Now weve got the momentum. Reporter what is one word would you use to describe her . I would say selfless. I think everything she does is. Is for the team. Reporter wambach craves the cup and the storybook ending but surprisingly not for her. I want it to be a young player thats going to lead us into the next generation of many worlds cup championships and many gold medal championships.

Rory mcelroy and Jordan Spieth are the number one and two ranked golfers in the world. Each has a lucrative apparel contract. One is with the industry leader, the other with an upstart that continues to cut an ever bigger piece of the pie for itself. Heres don dahler. Reporter with victories in two consecutive majors this year, jordan speith is on the verge of golf superstardom. When he won the masters, he was wearing no fewer than 16 under armour logos. The upandcoming Sports Apparel company took a chance and signed the now 21year old golfer before he turned pro in 2013. Eamon lynch, editor of golf. Com, says that was the corporate equivalent of a holeinone. If youre the c. E. O. Of a major brand looking at Jordan Spieth, youre seeing a talented, good looking all american 21yearold kid whos good to the fans, good to sponsors. Reporter after speith won the masters, under armour stock rose 3 a share, their first retail golf shoe sold out in record time, and golfrelated sales are up 50 over last year. The baltimorebased company sponsors a number of big names including lindsey vonn, cam newton, tom brady and n. B. A. Champion steph curry many of whom were also signed before they became stars. Its what i need to do. Reporter at 26, world number one player rory mcilroy has already won four majors. He is one of the biggest stars in the nike galaxy and joins the likes of tiger woods, lebron james and kobe bryant. But when it comes to athletic wear, nike is also number one with revenue close to 28 billion last year. Under armour recently overtook adidas as number two, but reported revenue just over 3 billion. Daniel kaplan is the finance editor of the sports business journal. Looking at any kind of rivals, adidas, under armour, how dominant is nike really . Well, nike is still the really dominant player in Sports Apparel and sneakers and sports branding and athlete endorsements, but obviously under armour is nipping at their heels. Under armour is definitely a millenial brand. Its a brand for generation z. Reporter and while tiger woods was considered the greatest golfer of his generation, analysts say problems on and off the golf course have diminished his commercial appeal. I dont think sponsors right now look at him the same way they used to, or certainly not the way they look at Jordan Spieth. Reporter spieth says its too early to talk about a decadeslong rivalry between him and mcilroy, but millions of golf fans and two corporate sponsors see them as the twosome for the future good for the game, good for business.
