Boston and the surrounding area have their own Smooth unit of length
The Smooth measure of length, approximately 1.7 m, was invented by MIT students in the 1950s and named after a freshman who tried to get into the student fraternity. As a test, the students measured the Harvard Bridge connecting Boston to Cambridge with that guy, concluding the bridge is 364.4 Smoot + one ear. The markings are still painted on the bridge.
