There was a pic here not too long ago of the new IED......a 4x8 sheet of plywood made too look like a mouse trap with a cold beer on it in a tent city near them.......
Funny picture.
Also I seem to remember a bigger version of the speedhook snares for coyote size critters.......
Here is the concept....for fishing.
