Plane Sight HDR

For years I have seen these planes when I was on bart, but I could not figure out where the were. I was doing research for a different photo when I looked up and there they were. Right on top of a self storage. A project was in the works. I just wish I would have had a chance to shoot the yellow bi plane that was on top of the Brenden Theater in Concord. I have always woundered why they took it down and what they did with it?
