We have mystery holes in the yard. We thought maybe it was a snake issue, but the holes don't go anywhere. They are shallow little pockets scattered all over the place!
It's like some small light-weight prankster has hopped across the yard on a pogo-stick.
Yesterday, I saw a chipmunk scurry across the yard and jump straight into the bushes in my neighbor's yard, and today I researched random holes and discovered that chipmunks make those kinds of holes.
The other culprit could be a pine vole.
Pine vole? At least Chip and Dale are cute. I'm not so sure about a vole.
Of course, I'd really rather entertain the idea of Martians hopping around on pogo-sticks.
