That is WEIRD!
It was all so foreign to me and my wife. We were used to hunting in Colorado where you buy a license and go hunting, usually on federal or state land.
But in Texas almost all land is privately owned. Not only do you need a license but you had to buy/lease rights to go hunting on the owners property. This particular guy owned his own property and that is why he kept the blind there all season and fed the deer in the summer. He was killing his own almost domesticated animals.
