Bike Becomes Rack

I've seen this a few times before and happened to have my camera with me today so I snapped a shot. It's an old ten-speed that is cemented into someone's front lawn on Porter Avenue here in Buffalo. The first time I saw this I just assumed it was a sculpture or someone's personal monument to bicycling. But on other occasions I've seen bikes locked to it...a bike that actually became a stationary object to which other bikes can be secured. A bike rack. Ingenious.
