Photo by myself around 42nd Street and Sixth Avenue.
I got a nice wave from some visitors while walking around, the other day.
Double decker open air tour buses are a familiar sight here. They are also known to visit Brooklyn and Harlem.
Viewing the streets from high up allows you to see more of a neighborhood, but it's no substitute for walking around on the sidewalks.
