A little background information:

The Fairmount Park System comprises the largest amount of green space within the city limits of any city in the world.

Today, (April 5th, 2008) there was a massive "Philly Spring Clean-up" effort all over town; I helped out along the Wissahickon.

The Wissahickon Valley is a part of the Fairmount Park System...and one of my favorite places.
(It's only about a 15 minute drive from my house, unless it's "Rush" Hour)

Bear in mind that all of these pictures were taken in the middle of Philadelphia...
