I can understand how you feel. And I think I would invest in the can of whip-ass too!
I am not fortunate enough to have ladder stands and I hunt from the ground. I have several ground blinds in strategic areas on my property. One particular ground blind has a milk crate embedded into the hill side next to a large maple. I have branches and stuff piled around for concealment. About two weeks ago I make my way in to this blind while it is still dark. When it gets light enough to see I notice something is not quite right. It looks like something was dragged right by my blind. Upon further investigation I see it is the path of an ATV. The driver couldn't go along the path because of a downed tree so he went around - two feet further he would have hit my crate and probably have capsized - that's how well concealed it was. It was a cold morning but I was warm because I was steaming! Didn't see any deer that morning either. When I decided to go in for lunch I found a bag of chew tobacco on the trail. Oh boy was I mad! Why can't people stay off private property? I respect others property....
I'm pretty sure I know who came thru on the ATV. I caught him about two years ago . You'd think he would have learned. Well, during the break between archery and gun season there will be some trees cut across the main path. That will keep him out. Also, a strategically placed game camera may give clues to who is trespassing otherwise...

tresspassers and poachers suck sounds like you need to spend some time snooping to find these morons and send them to the big house

I'd be pi$$ed as well ,espeacially if it was my land .But don't give up yet you just never know what can happen. Thieves are everywhere maybe you should put up a game cam and try getting pic's of them.
