Urban Ore Ecopark in Berkeley, California.
Huge warehouse and yard filled with unwanted building materials and home goods, that can be recycled and reused. Brilliant idea. Sometimes a real treasure can be purchased for pennies.
To my surprise, place was really busy. It's great to see that not all of civilization junk ends up in landfills.
Place has a very Berkleyish feel to it - staff rides skateboards around the warehouse :)
