Actually, I meant the land speeder! ;o)
It's at Disney-MGM, Florida, near the Star Wars ride. They also have about a half-scale AT-AT (4-legged Imperial Walker from the Hoth battle) that seems to have left a footprint or two in the asphalt.
10 years ago they had the "boat" with the walking plank from RotJ in the same area, but no more; I don't recall them having the speeder bike at that time. The bike is better because you can get on it :)
