ZG, there are several empty cans on ebay. I'm sure someone on here would be able to build a hat from them.....
I think my local Kawasaki shop had them on display when the soda first cam out. As kids, we would stop in that shop just to check things out. The trip across the street to the Yamaha/shop shop was better since Yamaha had the Motobike and Honda had the kick-n-go.
