Re: VERY IMPORTANT. PLEASE READ!!!
if the landowner does own the property and signs were posted, I would think tracking down the owners of the rigs would be the first step. He could even use the picture shown in the paper. Begin to charge each one identified (criminal case) and I'll bet the accused will begin to sing like birds on the remaining drivers. Once criminal case is complete, begin civil case- this is where the owner would have most support, due to jury and local support of environmentalists. Include the dj,station, and its parent company in the suit. Set monetary claims in the 7 figure range.
FWIW- I am not an anti-off road fanatic, but it is people like this that give a bad name to the rest of the good guys.
