I definitely agree with the others about the liability issue. maybe tell a little fib and put it on your insurance company. say you just renewed your policy and inquired about it and they thought it was a very bad idea.
I own a hunting property with numerous tree stands on it and I was concerned about liability so I asked my insurance agent about it and the first thing he said is you give nobody permission to be on it and better yet post it too which I did. according to him as long as I don't intentionally create a dangerous situation I have nothing to worry about. they would be trespassing. it's unfortunate the way things have to be today.
