I ride a carveboard. I got it when I moved away from the ocean and couldn't surf anymore. I love it so much, if you've got a good hill near you it's the best thing in the world. They are a bit pricy (about as much as a surfboard), but worth every penny. If you surf but can't get to the waves often enough, get one of these, and you will not regret it.
