There's a house a few blocks over that's been vacant for... pretty much forever... long before the market took a nose dive into the hot, molten pool of metal that is the current economy, at least. It reminds me from that scene in Prince Caspian when they go back to Narnia and everything's overgrown and nature has taken back all the buildings. It makes me wonder if this is where C. S. Lewis got the idea.

See? There really is a house back there.
