Our club is in a county park...no lease...just an agreement that we maintain that part of the park.. mowing etc.

You do not have to be a club member to fly at the field... but the county requires that you are an AMA member to fly there....
We have been given permission to call the local authorities to have someone removed if they are flying without AMA..... we have never done this.....

I don't know how all the legaleeze reads, but that is what it is at our spot
