I don't see it affecting AirVenture. The EAA typically brings in their own crew for Oshkosh. I've already heard from up there, that there should be no noticeable changes. I guess we'll see as we get closer.
I like your Air-Adventure. We could probably get some press on that, "Adventure Pilots take on Air-AdVenture with the simple and easy to use iFly GPS". Have a great weekend.
