Roller Coasters are great but they are restricted to tracks at amusement parks. This is so cool because these roller coaster cars can go anywhere!

It turns our that Mini Coopers make great Roller coaster car transports. Who would have thunk it. My idea goes a little further. I would do the same thing but substitute four wheelers for the Mini Coopers. Then you could have a swamp roller coaster. Just sayin'.
