Two semi-related anecdotes:
1. A New Yorker acquaintence of mine (never knew him long enough to call him a friend- he has since moved to someplace else) once got out of a scuffle on the streets of DC using a time-honored tactic of Brooklyn natives throughout history: start the loudest, most obscenity-laced, threatening rant you can manage.
The obvious problem I saw with this is that it is a big game of chicken. If the other guy doesn't blink and instead pulls a weapon, you're in a pickle.
2. Another New Yorker friend of mine used to commute from Long Island (pronounced Lawn Guy Land) to St. Johns College every day. The way he avoided be hassled on the subway? Sit in a corner, snapping your fingers and muttering to yourself. Occasionally yell "F***!" at the top of your lungs.
Worked wonders. It probably helped that he is about 6'2", a good deal of it muscle, with long, kinda ratty blonde hair.
Naturally, he was an english lit grad student.
