It was a pretty typical weekend in Las Vegas, with Adele performing at Caesars Palace, U2 at the newly opened largest spherical structure in the world, NASCAR in town and the Raiders hosting the Patriots. With it came the traffic snarls — on foot or car — from every road closure, redirection or new fencing erected along the Las Vegas Strip as part of construction preparations for a Formula One race that is still a month away. The inaugural Las Vegas Grand Prix, if nothing else, will be a sensory overload of neon bright lights, roaring race cars and some of the wealthiest F1 fans in the world in attendance.
