The EAA has been drawing non-"flying" (I won't even limit it to non-EAA) visitors for over 20 years. I remember back in the 90's when to get to the "flight line" you needed to be an EAA or other qualified member. Even then that wasn't a good filter on the dolts who would do stupid things.
I didn't see the really bad rowdiness until the cafes started selling beer.
On the other hand, many of the things I've pressed for over the years have been adopted (probably not because I suggested them). You can gripe about golf carts now, but it is way improved over what it used to be with not only carts but CARS plowing through show center. This tram move is likely to be a disaster for this year, but it will end up being fixed in the long run. Oddly enough between Pelton's office and the heads of Vintage, Warbirds, and IAA, EAA management is pretty responsive and caring. A couple years back when we had a bit of turmoil going on down south I got emails from Pelton and personal phone calls from Connie Bowlin (head of Warbirds) and Michael Goulian (head of IAA) in response to emails sent to tehm.
