This old structure has a series of holes leading all the way up through the five stories, to an opening into the sky. a single tree grows right through the opening, rooted in the cracked cement and piled debris of bottles, bags, and feces. Besides a nice homeless fellow who lives on the top floor the building is left for wanderers and explorers like us. We drank and filled the walls with debris of our own like many have before us. The north Philadelphia building one block off 2nd and poplar is probably already demolished and dreaming of more sterile grounds.
