If I'm up in the city (Rochester), occasionally I'll see a large group on motorcycles on the freeways around town, 20 to 50 guys riding almost tire to tire and peg to peg at 70mph, like one big single entity. Amazing to see them ride like that yet inevitably somebody has to crowd them and tailgate. That is, until they get close to enough to notice the Hells Angels patches emblazoned across their backs. You'd think they just swooped up on an unmarked trooper and suddenly realized their mistake, OOPS, BREAK LIGHTS!
Seriously, it is truly unreal the way those guys ride. Kids with their crotch rockets and annoying little foreign "tuners" sporting no fear bumper stickers are not even in the same universe.
