RE: Illegal to fly?
Most flying site loss involves urban sprawl and noise issues more than anything.
A few get lost due to accidents and liability issues but if your armed with information from the AMA and the site owner and town council understand that they aren't going to loose thier house if something happens that goes a long way. The absolute best way is to invite some folks from the council or property owner or whatever out to see what its all about, put them on a trainer on a buddy box and feed them some burgers.
