Sorry if you think I'm overstating. There are occasional crashes at OSH proper and those are usually due to someone that gets slowed up but wont break from the conga line to keep their speed up, but the vast majority of crashes occur en-route. Every year, people die in IA, NE, KS, MO, IL and so on to get to OSH. But can you discount the people that die on their way to/from OSH and say that doesn't count?
300,000 people saw the Rolling Stones at Altamont in 1969. One fatality has tainted that show for all time, but I'll bet at least 5 to 7 people meet their maker on the way to or from Oshkosh every year.
And, no, I'm not trying to be the poo in the punchbowl, because I remember when that show was in Rockford before it was at Oshkosh...
OSH has become a show like Sturgis without the hot chicks - it costs about the same to hang out there for a week.
