Here, Lizard, Lizard...

So, I'm driving to Starbucks for another proofreading session for the soon-to-be-published 7th edition of  Issues In Internet Law (which by the way is going to be awesome!) when I spot ... THAT... walking along the sidewalk. I didn't stop to measure, but I'm guessing it was about four feet from head to tail. Either a very big lizard or a rather small alligator.
Anyone want to hazard a guess what it was?
