RE: Tough decision as a land owner.....
I would have to say that if it was family and I really wanted to get something worked out, I would not leave a damn voice mail. I woulds get together with them, tell them your concerns and listen to their side of the story. If you get your point accross and they still do not respect your wishes then its time to take more drastic action. If we can't even work things out with family and friends, how will we ever work thing out with others?
