I am in no way sticking up for the trespassers. I honestly think they should go to jail. I have hiked hunted and just plan walked alot of land public and private from Indiana to Florida out to the desert. I even road my quad on land in Mexico. Ever time i new i was on public land or land i had permission to be on. A few times i strayed over that line out west because there are no markings or tree to mark. I was not there long.
Like when i went to new Mexico. I stayed at a n RV park that bordered govt. land. The owner of the park gave me permission to be on his land and the land next to his owned by his buddy. He said the guy was OK with it as long as i did not tear any thing up. I was in the desert not much to tear up. but one day i crossed the line into the govt. Land i found out after i came back through under a road and saw a sign on the road.
I ever went back even went and told the office at the govt. park. I told them it was a mistake and would not happen again. They told me they had someone report it but it was OK.

There is no reason for anyone to be trespassing.
Now crossing a property line once or twice by mistake OK. But i doubt this was the first time the ATVers crossed the line.
