Go to any major American college football game, stay through halftime, and
you'll most likely find at least one group of uniformed musicians
cavorting about on the field. They'll play some music, they'll move
around in strange formations and patterns, and, with any luck, they'll
entertain you. These are the people of rec.arts.marching.band.college.
