Title: Didn't work for me
Review: I'm in northern California and have a winter vegetable garden going. Found an active gopher tunnel in my vegetable garden bed where I'd been losing vegetables for several weeks. Ran exhaust down the tunnel as instructed for over 30 minutes. Pulled the hose and opened up the tunnel. Within 20 minutes the gopher had plugged it back up. Tried it on two other holes and they also were plugged back up within an hour.
