Lots of static displays and various classes of air racing. The unlimiteds (mainly P51s, Bearcats, and Sea Furys) reach about 500mph 50-100 ft above the ground. The AF Thunderbirds performed last year and there was a low flyby by a B52. Here's some pics I took last year.
Don't wait too long. There are constant rumors that, because of insurance costs and other issues, their (RARA) days are numbered. This is the only air race in the US left.
