Hehe. No, I've never done it, but I did a see an episode Pigman not too long ago where he, Ted Nugent, and a few other guys went shooting pigs from a helicopter Rambo-style. Pigman and Uncle Ted were talking about how some people might see that episode and find it utterly disgusting that people would hunt game from a helicopter with scoped assault rifles, but then they went on to talk about the HUGE pig problem in states like Texas and how they obliterate crops and ruin land at mind-blowing rates and that the government actually WANTS people to shoot more wild pigs because they have no bag limit on them, which is all very true... but still... I don't think I could bring myself to hang out of a helicopter and mow the little bastards down. Maybe it IS totally legal to do that, but I'd feel like a total piece of shit doing it. That's just "cheating", man, lol.
Why not just round 'em all up and make pork chops for everyone?
