Many aircraft manufacturers have displays
Portapottys are located throughout the camping area. This is in addition to a very large restroom/shower building.
The fly-in has its very own daily newspaper as well as hourly e-mail announcements.
Everyone who enters the convention area must prove that they have paid admission - I was issued a one-week bracelet as proof. I slept with it on and it didn't come off and it wasn't uncomfortable.
There it is - now share.
Treky with his blindfold - keeps the sun out and helps keep cool.
This is the large restroom that I was talking about. See those mirrors on the side of the building - Each position also has a smart phone recharge connection - very neat. Enough campgrounds - Much airplanes next.
