I can get really phuqued up sitting in a chair with a twelve pack and a shotgun waiting for the little buggers to start pushing up soil in my general direction! I am thankful beer is so cheap!
In my younger days, I'd dig into a gopher mound, leave the tunnel open, step back a little ways and wait. Wouldn't be long before you would see dirt being pushed from inside the tunnel to stop it up. High brass #6's worked very well.
