I voted "maybe" and let me tell you why.
I just now got back from hog hunt on a friend's property in Okeechobee, FL. He has about 85 acres or so. There are no fences. Yes, there are cattle/barb-wire fences, but these are not high, and so open that hogs walk under them and thus roam all over the place. He also has some chickens and cattle, and feeds them. The hogs roam all over that part of the county, and try to eat some of the cattle's food. He told us that for the last couple of evenings, some hogs have come to the same area, so he invited us to go. In Texas, we have automatic game feeders that go off every morning and every afternoon. It's kinda like a dinner bell of sorts because once the feeders go off, the deer/hogs come running in. Well, here at my friend's place, there was no "dinner bell." We just waited the old fashion way to see when, or if, they could show up. Sure enough, the hogs came, although much later than he usually saw them. I would say that they came around 8:15pm. He said that these looked like a different group of hogs. There were about 8 to 10 hogs, and I would say that there were about 3 different sizes: Big, medium, and small. I let my dad shoot, and he shot a medium looking one at about 50 to 60 yards away. It turned out that this medium hog was a female that weight an estimated 150 pounds (which means the small ones must have been about 40 to 70 pounds - next time I'd rather shoot a small one.) Now, was it fun? Yes. Was it a true hunt? Yea, I'd say so. There was no guaranty that they would show up. It wasn't a trophy hog, but I don't care. We did it just for fun.
Now, would I hunt a "pen raised" hog? Remember, I voted maybe, and here is why I might shoot such a hog. I don't particularly mind shooting pen raised/fenced hogs IF and ONLY IF I do so without considering it to be a "hunt." And I say this because, rather than going to the store to buy pork, I'd rather shoot something that hasn't been injected with God knows what from the USDA, etc. In other words, if you shoot such a hog FOR FOOD and YOU DON'T BRAG about shooting such a hog, and if you ARE OPEN and HONEST about shooting that hog under those conditions, then I don't care. To put it another words, I consider such shooting to be one step (if that) above slaughtering. I'd rather shoot a pen raised hog than have it slaughtered. It's more fun shooting it with a gun than it is slitting its throat with a knife.
Again, I make a clear distinction between hunting and shooting. What I am saying is that if people want to shoot "ole Fred" then that's fine by me. HOWEVER, if people want to make such a BIG DEAL about it, and brag about it, and claim that they hunted it, then I find that silly.
