So... guys wanted to nail her. Guys said hi. She made it clear it she was not interested. 99% of them dropped it and moved on.
Some of the guys were out of line, but there were relatively few cases of out and out harassment. As long as the guy backs off when the woman ignores him, I'd say it's fine. It might be annoying, but it's not like there aren't tons of annoying things in NYC either way.
