The Arcata, CA, Kinetic Sculpture Race: bicycle-powered land-and-sea

Hi, kids! Well...in a place far, far away (well, California), there is a strange little town where a lot of artists and craftspeople live...especially those who know how to do welding with a blow-torch. And they have a very strange way of celebrating the end of the long rainy winter: they have a bicycle race! 
But the thing is, the bicycles they use...have to be able to transform with floating supports so that they can travel on the water too. It's the Kinetic Sculpture Race.

Here are some of the..."contestants." I saw some of these...and it was strange!
