Tunes in and tuned out!
I would worry more about being run over by traffic than having a thief rob me. This is a busy city with people, traffic, and bike messengers coming at you from all directions. Stay alert and be in the moment, NYU's "campus" are the streets of Greenwich Village hardly the isolated campus that most rural Universities offer. While I got your attention, I wish all those same youngsters would pay more attention while walking while chatting endlessly about nothing on their cell phones, the tobacco of the 21st century.
