As I understand it, the smaller species of ground squirrels are commonly known as gophers in many parts of the country (i.e. Minnesota "Golden Gophers"). Some places they are known as "picket pins," too.

I prefer the kind we have down here (California Ground Squirrels), which are at least twice as wide and tall as a "gopher"--MUCH better targets! One of the FEW advantages for a shooter living in CA....
