Follow us as we begin walking the streets of Center City Philadelphia weekly. When our walks are complete, we will have touched foot on every street in Center City, documenting all things green. Documented items will be included on our map. We will begin walking the week September 6th 2010. Our first walk will begin at Front & South Streets and we will walk the length of South Street from Front to 27th Street. Follow this walk virtually and join us in subsequent walks.
