If I get to MY hunting spot, and there's a truck already there, I call the CO and have the poacher arrested. We own the spot.
What was really funny was the first night we'd taken possession, we came back from eating dinner and there were a bunch of guys out in the field. I looked through the binos, and there was a white Blazer and half a dozen guys in camo. It was just after sundown. The first thing I did was light my Coleman lantern. That let them know somebody was now living at the old place. Their only exit from the place was not blocked.
The guys out in the field reacted by gunning the Blazer and heading off towards an end of the pasture that I knew was a dead end. They came back to the same spot they'd been previously a few minutes later.
By this time I'd grabbed a 6V lantern, my camo field jacket and a hatchet. I got within less than 50 yards of the Blazer. They were arguing in the dark over what to do and accusing each other of getting them in this fix. They didn't see me close to within 20 yards. I then flicked on the big flashlight, and they all got that deer-in-headlights pose.
"Good evening, Gentlemen." I'm roughly the dimensions of John Wayne in his latter years. I was at least a couple inches taller and I out weighed everyone there by a good hundred pounds. The hatchet handle was protruding from my field jacket.
"Who are you?" Asked one of the guys who had appointed himself spokesman.
I introduced myself.
"Do you know Orey X_____"
"Yes, I am quite familiar with Oren J. X____" I replied. " In fact I saw him not half an hour ago."
"Did Orey give you permission to hunt here?" The fellow took a step towards me, and the crowd started to close a little.
"No." I said. "The place is under new ownership."
"And who might that be?"
"Me." I replied. "We own the place now."
I then led them out of the place and explained the new property lines. It turned out these guys were my next door neighbors. I later went and talked to their patriarch, who apologized for the transgression and promised that there would be no repeats. He kept his word, and I have have not had trouble from his kin since. Until the trailer burned in 2003, I would sit at my thoughtful spot and trade owl hoots with them from across the holler.
Prior to getting our place, I'd hunted public land and various private plots over the years. I can tell you that it was pretty disheartening to do all the pre-season scouting in a spot and then have the turn-out filled with trucks on Opening Day, but there is not a whole lot you can do. I always erred on the side of safety and never deliberately hunted behind another turkey hunter.
