Went to the legendary Dust Bowl ditch in Philly with Craig and Larry last week. Epic spot; even more epic graffiti. Janky roll-ins, curbs, and wallrides abound.
There's at least 3 different sections of it, all connected by tunnels and underpasses. It'd be sick if someone filmed a line through the whole thing.
One part looked like it would be super fun, but it was flooded out when we were there. Maybe next time.
