Last year I really enjoyed watching the ultralights fly. They had powered parachutes over there too. The announcer was actually really entertaining, himself a long time ultralight pilot. Im not an ultralight guy either, but I enjoyed that. I echo the airshow, it is not to be missed. Watching all the airplanes taking off and landing is almost as entertaining as the airshow itself, as Rick Durden says in the latest pilotcast, some of the best entertainment on the field is to get a 12 pack of beer and a chair and sit next to the runway and watch airplanes come and go. Some you will wish you were as good as that guy, some you will be amazed at.
The booths and everything are pretty interesting, I unfortunately never made it to the Warbirds section or the Fly Market, only there a day and a half last year.
