I understand your frustration. My family owns a fairly large (130) acres of property with a few gas lines running through it. Every year I deal with the same thing. Sitting in my stand and suddenly here comes 15 quads and dirtbikes ripping down the gas line. I have had it out with these people numerous times. I started out by trying to be nice and explaining to them that they have all spring summer and early fall to ride and hunters only have the woods for a short time so try to be courteous and let us hunt undisturbed. After this tactic did not work I tried to explain to them that it is private property and they are not permitted on it. Their rebuttle was that they are on the gas line and they can ride it if they want to. After trying to explain to them that the gas company has the right of way, not them, it STILL DID NOT get through their thick skulls!! I have tried contacting authorites and they say there is nothing we can do. Does anyone have an idea?
