Screencap from a short film shot at the Packard plant in Detroit

Packard gave up on its automotive plant in Detroit in 1956, but the 3,500,000-square-foot complex of reinforced concrete remains - if only as remains. It is perhaps just as famous for being ruins as it was when it built cars, still attracting plenty of attention from entrepreneurs, paintballers, vandals and urban spelunkers.

Creative types love them some Packard Plant, too, evidenced by the short film produced by Cantini Pictures when they wanted to test out a homemade motorcycle and an aerial drone. The result is a few minutes of "motocross meets the monument."

Check it out in the video below. And in case it isn't obvious, you probably shouldn't try this at home... nor at the Packard plant. For a more traditional history with lots of photos, a piece in the Detroit Free Press can fill you in.
