The one guy that we clear hogs for wants us to leave the hogs where they fall. We got 6 pigs the other night and left them right where they fell. He wants them left there for coyote bait I guess, so we oblidge. There is a problem with pigs around here; we found one area, about three acres, that was completely rooted up and wallered on. We're going out again this weekend and hopefully we will get some more.
On another place that I hunt, they actually brought helicopters in to dispatch hogs. After the 'hunt' they piled them all up and just left them there to rot. If I get a small pig, I will usually take it home with me and make sausage out of it, but when they get bigger they just start to taste like crap.
