Rick, that sounds like a heck of a lot more fun than any of the other suggestions.

I use to trap turkeys with old bed springs. the whole set, turn upside down so the spring cone is going to the ground. you will need to have it up off the ground a couple of inches. throw corn under, they will stick their heads down spring cone and can't get out. probably something that should be checked often. I am NO adc guy but this might help.

Gotta say I havent heard of that one.
