Never seen a trespasser yet that wasn't up to no good, HUNTING ON LAND THEY DON'T HAVE PERMISSION TO.

If you can't Afford a Modern GPS that has a chip for property lines then at least visit the local County Clerks office and look at a plat book of the area you want to hunt. they all have the land owners name on the parcel Except maybe those little tiny lots in Detroit.
Then if you are hunting some ones private property with permission make sure they show you their boundary lines.

Last years late bow season which I don't hunt My wife called to me that some one was out messing around my pole barn in the back yard. I went out there and here is this camo clad clown with a bow. Said he had shot a deer and wanted permission to track it. YA I BET IT HID IN MY POLE BARN. I ******ed him off the place told him that the sheriff would have his picture before the day was over so not to be surprised when they pulled him over on the road.

Turns out he had indeed shot a deer a 1/2 mile down the road and had trespassed right past a couple of my neighbor's places and also by some of my signs too.
He was around my barn because that is the first building he was near I figure.
Never the less I swore out a complaint of trespassing and then went to court when he felt he could fight it and win. but lost because I DID show up.
