Collecting found objects, after a fire....

I'm always on the search for found objects to use in my pieces. Last week while in Philadelphia, I visited Sander's Supply which carries mostly restaurant equipment but is a great place to find old junk. I'd been there a few times before but this time ventured to the 6th floor where they had a fire back in April '09. Since the building is made mostly of reinforced concrete, it was pretty intact, but everything else, the floors, walls and ceilings were burned up. I found some pretty cool pieces in the charred rubble. The kind of pieces that are perfect for me- nondescript with a lovely patina. I could, should have, collected more.
