While looking through a scooter messageboard, I found a link to these pictures of scooters and motorbikes around Tokyo. When I got down to the bottom of the page, I found a great picture of a supercub all set up for ramen delivery!

I had explained this vehicle to several people, but now I have a picture of the real deal. There is also a picture of a supercub that looks to have been modified to accomodate a surfboard.
