I know of someone that sued because they were deer hunting their land without permission. The guy went and got local estimates per acre for leasing land, and sued that trespasser for that amount for every acre of land he owned. He won, because he said if I wanted people to hunt my land, I could have leased it out for this amount, which is the going rate in this area, he also pressed charges for Tresspassing, which if I remember right, he had to be found guilty of before the civil suit.
