On the Hudson Greenway (MUP), near the NYPD tow pound, I was riding downtown, but temporarily in the uptown line to pass some little kids who looked their training wheels had just been taken off. A roadie going uptown apparently didn't like this despite the fact that, well, that's how it's done around there. He sat up, spread his arms wide then contorted his face into a nasty expression and gave me the finger. WTF? Dude had enough time and room to spread out like that, so what's the problem? I'll be honest, I had no idea how to react as it seemed such a bizarre, pointless exercise on finger-man's part. Really! it's possibly the widest part of the entire Greenway at that spot.
