One thing AMA insurance has been doing forever is making the site owner happier about who they're inviting as guests onto their property. We're guests everwhere we go and we do something that's often a bit strange to the landowners. It's often an unknown to them. Explaining our hobby and then playing the "we have insurance to protect you" card goes a long way. I've been a member of a lot of clubs and I really can't remember a one that didn't get their flying site without the help that argument gave.
