I'll bet it was perturbed! What a shocking and inexplicable experience for a poor groundhog to be subjected to.

Bert, I can understand your concerns about the vegetable garden. If I had a vegetable garden I would be much more worried about groundhogs. What you have here is a simple conflict of interest. I don't see any easy solution. :-) By the way, I suspect the groundhog was less than thrilled with your appearance as well.
