Wow. That's about as bad as it gets. Talk about looking a gift horse in the mouth.
I was on the same lease in Live Oak County from 10+ years on my own. 15+ in total. I inherited my dad's spot when I was in my early 20s. 5 guns. 1100 acres. Low fence. We didn't feed protein, but we tried out best to manage the herd. And we did a TON to improve the property. We were constantly working on the old cabin that we stayed in. Fixed a ton of fences. Mowed senderos. Hell, I rented a dozer one year and cleared a bunch of brush and mesquite for him. We were allotted one trophy buck each. But, we never shot more than two total in a year. We started to see better deer and shot a few in the low 160 range. We'd see the same deer and started to do a good job of targeting / managing the right ones. We had seen this one really nice mainframe 10 with distinctive split brow tines. We aged him at 6.5. He was a regular at one particular location. Then, he vanished. And this was pre-rut by a wide margin. It was around 2005, so I went and bought my first game camera. Set it up near the feeder of that blind to see if I could catch him on camera. Instead, I caught two hunters dragging a bullshit 3-yo 8-pt to their truck.
Who knows how long that landowner had been running day hunts. We had a handshake contract with him, so there was no recourse. But, what a shitty thing to do. Out of our blinds and under our feeders. Needless to say, that was the last year we hunted there.
