Foamhenge is one of those kitschy roadside attractions you visit on a spontaneous road trip with a group of friends or a date. It's also a fun place for a pit stop to take photos on the way to or from The Natural Bridge.
The sculpture, made entirely of molded styrofoam by artist Mark Cline, is a life-sized replica of the original across the pond. I've heard that the stones are placed in precisely the same astronomically-aligned formation as the original.
If you go, it's worth also checking out Cline's other zany attractions, Dinosaur Kingdom and Haunted Museum.
