They're back!

I took this photo of Ted and Sam because I thought it was so sweet how Sam gets so excited each week to help Ted mow the lawn. Tessa just follows them around too. However, I am publishing this picture because Ted's nemeses have returned. If you look between the lawnmower and Sam you can see the holes in the lawn. We have trapped, flooded, poisoned, and even blown up these holes hoping to eradicate the gophers. But to no avail. They are back. Their holes are destroying our lawn. I am ready to give up. The point goes to the gophers in my book. I don't ask Ted about it. I know it makes him crazy, and what is he going to do about it? What is the next step after blowing them up????
