Well let's see. Out west they can confiscate your vehicle, rifle and all possessions in the vehicle, least that is what a couple of guides told me while hunting with them. That seems pretty stiff to me. I am a bit easier, how about a $3,000 fine and loss of hunting privileges for a year?
That should not bother any ethical hunter as an ethical hunter does not trespass. I would sure think it would get even the most determined trespassers to exercise some brain activity mulling it over to decide if it is worth it.
We bought most of the land we own, busted our butt's to pay it off before retirement. We did inherit a 60 acre tract from my wife's parents. We did not spend hundreds of thousands of dollars for it to have anyone who buys a hunting licence, atv or whatever to run all over it.
Are you a landowner? Have you ever had a trespasser try to run you off your own land? I have. Have you ever had to clean up garbage left by people trespassing on your land? I have. Have you ever had people on ATV's ruin your trails making ruts and damaging water management ditches on your property? I have. I could go on.
So excuse me if I have stiff standards where trespassing is concerned, I have lots of first hand experience with people trespassing on me and then I am left to clean up the messes, all while the law does virtually nothing to them.
