As an immigrant who lived in south(NC), midwest(Colorado) & west(CA), each of the regions are very unique. In south most people greet you & nod at strangers while walking on streets. I got used to this habit & in midwest/west when i nod, many times it will be met with blank stares. Some of my friends who nodded out of practice in India got into hilarious situations where people became suspicious. Overall my impression is Americans of all ages/sex are very outgoing (except for young women who probably are afraid of getting unwanted attention) when compared to people in Europe/India/China.
