I agree. In the early 90's I could still find a few land owners who welcomed responsible hunters onto their farms/ranches to take wild hogs. They would do so without charging a fee or some would charge $1 so that legally it was a contract and there was less liability. Then some folks started making money, and for a while I couldn't blame them, especially all the peanut farmers down south that the hogs had literally put out of business. Sorgum, Maize, you name it, the hogs ate it, but peanuts; hog heaven. I have seen a sounder of hogs simply mow down waist high Sorghum an acre a day. There was a time when farmers wanted you to bring your brother, your friends and whoever else had a rifle to come and shoot a hog or two. There was always the expectation that you ate what you shot and those folks who just wanted to shoot as many as they could and leave them where they lay weren't welcome.That’s correct - the carcasses stay where they lay. When they shoot by helicopter they just leave them.
As an aside,we have always had hogs in our area. “Back in the day” most ranch land was operated and owned by a local resident. All the landowners shot and killed hogs keeping the population in check.
As ranching became less profitable and land more valuable, locals sold to folks from urban areas. Most of these new owners were absentee - and did not operate or tend the land personally. The result was that fewer hogs were killed. Some landowners allowed hogs to proliferate so they could “hunt all year.”
Clearly these things combined led to a bloom in the wild hog population. Once the genie is out of the bottle it’s hard to put it back in. So now hogs are a bigger nuisance issue and do more damage to crops, fences, and pasture - not to mention the wildlife they disrupt through predation or habitat destruction.
It’s my opinion that, at least locally, this tipping point was in the late 80’s to early 90’s.
However, when your neighbor buys a dozen hogs that were trapped on someone else's land and tells you that they'll stay on his side of the fence and he's getting several hundred dollars off of each person that come out to shoot them, it gets harder and harder to not do the same. Then there are the investors who sink a bunch of money into hog hunting, boasting about building first class accommodations with five star chefs, wine cellars and guides who do everything for you, before and after you pull the trigger. Well, then comes my objection, or at least my lack of patronage. For the urban areas and suburbs here in Texas it's quite a novelty to have deer roaming around the local parks, so they start feeding them corn. But when they start to come around the house, eating your pretty rose bushes then there's a problem. And there's always one environmentalist who says all they need is some birth control to keep their numbers in check. Anyway, what happens when the hogs start moving in to get all that deer corn that's lying around? Wait until those hogs start plowing up all that nice golf grass they planted around their MacMansion. No joke, it's happening in the same county I live in.
I think that any size hog will make good sausage if you understand that it's important to dress it out quickly, including skinning, not for the hide but to get it cooled down. A bag or two of dry ice placed in the body cavity does wonders and if you've got somewhere that has a walk in freezer even better. If you're doing it primitive, pre-1840, etc. or are just going to pack it out then the ones under 100 pounds live weight are your best option. A 40 pounder live will be the perfect size after being quartered to go on a modest sized BBQ and with a little seasoning is a meal to remember.
