There is a block in Southeast PDX off Clay street between second and third that is full of urban ruins. The space in the coming months is rumored to turn into a highrise, but currently the broken walls are a shelter for the homeless, teenage angst, and if you're lucky enough to go visit the ruins on a Sunday a dance crew. It's one of the coolest city blocks i've ever seen - filling some weird space between a modern art exhibit and a public restroom.
I threw a couple of these photographs up on the shop. You can check them out here.
