Sherry, The Bluedog & I took off this afternoon and headed over to the Blue Hole on Big Pine Key. The Blue Hole is located in the Big Pine Key National Wildlife Preserve. It was a quarry at one time years ago, filled with water, and is now a habitat for alligators, numerous bird life and of course, Key Deer. It was a nice little walk, and The Bluedog really enjoyed all of the really good deer smells.
