I do Oshkosh every two years, and have been five times now. Going like that gives things time to change. Fabulous place, full of interesting people, but the trouble with many visitors there is that their avaition knowledge is pretty much nil. Also, if you arrive on the Sunday, be prepared to see some absolutely HORRENDOUS flying, as 2,000 odd aircraft arrive. People running short of fuel, coming the wrong way round the circuit,etc., and if it's very hot, which it normally is, then huge thermals off the runways interfering with smooth 180 turns to finals. My problem is that every time bar one, there has been an awful accident in front of me. This year was no exception with two Mustangs [P51] using the same piece of sky, unbeknown to each other, resulting in the death of one pilot. I videoed the whole sequence from lead in to aftermath, and the NTSB have it. Don't care much if I don't get it back. But, as people say, you have to go. It's an event unlike any other.
