Just my opinion:
I am an avid black powder shooter. There is the biggest black powder shoot in the country and likely the world, in Friendship, IN. I am in California, so I haven't made the trek out there, though it really is an experience. I have friends who have been though. They had a long drive though. We also have smaller shoots locally that folks nearby or just out of state come to. It is not the Friendship shoot though, not anywhere near. But the Friendship shoot doesn't move.
So, Flite Fest is the same way, it IS the big deal, but it doesn't move around. I wouldn't mind to have "chapter fly ins" though. There could be a SoCal one, NorCal one, PNW, Southwest, Midwest, Northeast, Southeast etc... But the big FF needs to stay in OH, where its roots belong.
