Another find, courtesy of the awesome Roadside America app, we hit this oddity a few weeks back when we were in Princeton for the afternoon. It is a replica of a human molar and stands an impressive 15 feet tall. It is on Sloan Avenue, in front of an industrial-type warehouse facility, across the street from the train station, and was very easy to find. Standing next to it, there are statues of a couple, looking very confused. I would be confused too if I suddenly discovered a fifteen foot tall tooth on the side of the road!
