We witnessed a musical battle around 7 a.m. in a public campground in Alberta once. A guy was playing rock music -- LOUD -- as he made breakfast, etc. A fellow next to him asked him to turn it down and received a "FY" answer. So the second fellow turned on HIS stereo. Opera. Wagner. And a much bigger setup.

I don't know the resolution of the incident -- we packed up and left before fists started flying.
