Amen to that, Bro. Made me think of my favorite places back then. One was in a rock quarry, not ideal facility-wise. Attraction was rather great people to fly with, no club with attendant roolze and rulers. It's now buried under a housing tract. Another is still there, a decent though rustic slope site with no cleared landing area (back then) - one selected the softest looking piece of scrub to kamikaze into. Best part about it was I could go there with my kids and buds that were either new to model flying or irregulars about it. It is now one of several sites controlled by a members-only club with all the usual baggage. Not that I couldn't join the club, but my particular reasons for liking the site are history.
Sure glad that mean guy, you and a few others were able to preserve your favorite flying place. Especially because you did it by showing people the merits of our hobby/sport and welcomed them in. It seems so much more sensible than, as KE observed, scaring public servants by trying to impress them with eye-widening insurance $$ numbers, and erecting obstacles to keep the people out.

You are giving 'park flyer' definition by demonstration. That definition is clear and comprehensive: a model airplane flown in a park ('park' can be generalized on, I won't) and be accepted by park administrators and other park users. Its physical and operating characteristics need to be adapted to fit the constraints imposed by careful consideration of each park's limitations. No different from any 'traditional' flying site. No AMA chartered club site is capable of supporting all of the vast array of model types flown, nor in many cases to the limits of their capabilities. Not even AMA's own uber-site in Muncie.
