I plan to arrive the Saturday before the event opens. Probably stay until Tuesday. Can only afford a couple days of vacation.
The BeechOwners list is a good source of information on Beech events at the beginning of the week.
Bonanzas and Baron's arrive on Saturday. The sky is thick with them. About 100 Beeches land in formation in a matter of minutes. Lotsa smaller Beeches show up that day, too.
There is a margarita & pizza party after the arrival on Saturday. 150-200 Beech owner/pilots attend.
Sunday (last year) Hawker-BeechCraft sponsored a barbeque. Music was poor, but food was good. There was a signup on the web. 100's of Beech people.
Monday was opening day. Beach Boys concert at 5pm.
If I could go all week, I would. But only able to go for a few days, I wouldn't miss the comraderie of camping in the Beech section of the North 40 at the beginning of the week.
