Dave, knowing you, if somebody were good hearted, and had good intentions, and took you up on cleaning the brush, you would let them hunt and fish.
But like I say, many want something for nothing. That's what public lakes are for.
Sounds like the bulk of your problem stems from you not living on the land and people take advantage of you for this reason. I don't either, and had a 15+- ish girl come riding right up to my small pond the other day. We had been shooting firearms not 5 minutes previously, and could have hit her.
