Plymouth Rock

We spent Labor Day with some friends down in Plymouth and so as normal tourists would we went to go see the rock.  I thought for a minute that maybe my mimosa with brunch was skewing my vision but no, it was not.  Plymouth rock is not some gigantic boulder, it's just a rock in a hole.  The tour lady was saying that it used to be much bigger, as big as the hole that it sits in but that erosion has gotten the best of it over the years.  Humph...I'm not so sure.
