It is much simpler to do the easy thing. Report the vandalism to the local law enforcement including fish & game. If you catch them in the act get an accurate description, vehicle license number or numbers and make model of vehicle. Then also post that information for all to see. Do not try to take matters into your own hands. Some of thse idiots out there who call themselves sportsman are armed to the teeth and I do not believe they would hesitate to use the weapon on you. Possibly justified in defending themselves. If you pack a digitial or film camera just take pictures if you have the time. Let law enforcement handle them and they will believe me. Just my 2 cents worth.
