i was born and raised in Mt. Airy. i used to take the R7 home all the time, regional rail (R lines) are very reliable, very comfortable and the R7 stops behind Temple's campus. you can get a montly rail card that covers regional rail as well as regular trains and buses, don't know how much it costs these days. Good choice for neighborhood NW Philadelphia is the nicest area of the city. lots of trees and parks there are some parts of Mt. airy, off of lincoln drive, where you almost forget your in a big city. enjoy
