So i took a ride yesterday on the 36 Trolley. Got off at UPenn and walked to the Subway. From the Subway I took the 100 out to the Suburb of Bryn Mawr (sp) Out there it's the suburbs. It's a lot different and lower density than your typical Texas suburbs even. Pretty crazy.
What struck me however is the amount of blight on some of the subway stops. Philly is a cool city but there is definitely a lot more they can do to fix up some of the neighborhoods. That is if they want to be fixed.
