There is quite a few localites that have banned model flying. Many have been brought about by arrogance, stupidity or just noisy models and the right people complaining. I think in one case a city councilmans kid had gotten hit by a glider (not hurt or anything) and they went on a crusade.
Your best bet is to get in contact with the flying site assistance folks at the AMA they deal with this on a dialy basis.
