Another interesting bit of rock art, maybe straight out of the Flintstones, is in the tourist center at the Rock of Ages in Graniteville, VT...of course. This is a large, active rock quary with a history/souvenir shop, outdoor exhibits of an old quary pit along with some of the equipment once used, and you can even take a sample chunk of granite with you (that's one way to clean up the old detritus!).
What journey is complete without a good dog dunking. This is probably a common sight for the lab owners out there, or anyone who knows Zeke.
