That is not a good idea. Innocent people will die when forgotten mines go off in a decade, and full auto weaponry is probably overkill. I can't imagine your aim is going to get any better when you're firing in full auto, unless you're far closer than you want to be.

Plus there are far easier solutions. Poisoned corn does about the same thing as mines, but with less risk (assuming you put up signs) and cost. Both are probably still bad ideas, though, because of the effect on other wildlife.

"forgotten" mines? Perish the thought. I'm thinking traps. like command detonated "kill the acre" measures.

I don't like poisoned bait for broadly similar reasons; I'd like more targeted slaughter. It's not easy to get a big gang that close together.

Don't encourage them
