I've been twice..'96 and '00
In '96 I was there for the whole deal. I really liked Wednesday, a practice day. Not as much crowd, and lots of flying. And it was a nice day. The next day the wind blew everything away, the tents, what a mess! After that we usually went out about 10~11 and were able to catch the freestyle and noon demos, and stick around for as many rounds of pattern as we wanted.
In '00, I was just there Thur-Sun...and did about the same 10~3 type routine. Missed some of the flying, but I was staying up a bit past my bedtime
The schedule is about the same every day, of course they have the awards Sunday...
What I usually base my stay on is the airline schedules....I fly Southwest, and getting a Sunday flight out takes some long term early reservations. So does flying in on Friday. So I do the Thursday/Monday thing and watch the TOC at my leisure. Seems like I can always find somethig to keep me busy when I'm not at Bennett!
