PITTSBURGH -- A typical day on Carnegie Mellon's campus.
I didn't get a chance to ask this guy what was up. I assume he was there for a event that was about to start, but maybe he was just out for a stroll.
CMU offers a music degree in bagpipes! The degree, started in 1990, is the only one in the world and has graduated 3 students through 2009. (I can't find data that's more current.) Some students just take lessons. Because bagpipes are phenomenally loud, students practice in a sound-proof basement studio on campus. Maybe this guy just couldn't take the closed in space anymore.
