MOLES . . . the enemy

Grab a cooler, tasty beverages, a lawn chair, and a pitchfork. When you see the ground moving, jab the pitch fork down just above where the movement was. Make sure you don't have to many tasty beverages first though; you don't want to put that pitchfork through your foot.

This works, but you need two pitchforks -preferably with the tines fairly close together. The first pitchfork goes down just behind where you see the tunnel moving so the varmint can't just reverse course on you. Then the killer pitchfork goes where you see the movement as it tries to get away.
Good luck.

(Actually I like the 12-guage idea better. More fun and noise!)
