The Talented Mr. Groundhog

If anyone out there has ever seen this, please let me know because it kind of freaked me out.  This afternoon, I saw a groundhog climb a tree.  I had no idea they had the ability to climb trees and it was a little creepy to witness.  I don't know if this was an abnormally gifted groundhog or if they can all do that, but I do know that I didn't like it.  It kind of makes me wonder what hidden talents other animals have that I don't know about.
