Happy Groundhogs Day

Have you ever seen a real groundhog?
I thought I had! I thought they were small like a prairie dog!
Boy was I in for a shock when Brian told me to look out the window and I saw this huge creature walking through our backyard! He was unlike anything I had ever seen before. He was huge and looked like a beaver without a tail. He mozied through our backyard and eventually went under our shed. Brian suggested it was a groundhog but I was convinced they were small.
We immediately went to google to see if we could figure out what this critter was. Sure enough, Brian was absolutely correct. It is common for groundhogs to live under sheds... imagine that. Another backyard pet?
