Okay, before some wag makes this point, the gator is missing a good chunk of its tail, so this is more like the left half of the anterior two-thirds of a gator. But that would make a lousy title. We might have more to say about this in the future, but for now, I’m going to let this 1000-word-equivalent speak for itself. Many thanks to Elizabeth Rega for the use of the gator.
