will happen, it's a question of when. we get hit every day with 100 tons of material coming in. and it's very small and we don't even notice it. but in 1908. a 65 meter wiped out a fair amount of trees but didn't kill anybody. it will happen again and it will be significant at some point. it's a question of one. there are many thing to worry about in life, and this is just one of them. you have to keep it in perspective. dan: what would it look like if one of these bigger ones were to hit. and do we have the technology now to detect these things? there are things i want to worry about and things i don't.
