The Wave by Street Surfing
This is kind of off topic, kind of on. This past off season, my brother turned me onto The Wave Board by Street Surfing. It's amazing how fluid it is, and how much it feels like a combo of surfing and snowboarding, and it's totally kept me in shape for the upcoming snowboarding season. I got it from my local skate shop, but my brother just bought a new one on their site at streetsurfing.com and used a code he found, BIGWAVE1, and saved 10% on the board and some new deckplates for his old one.
Just wanted to pass that along, it's a really cool way to stay in shape.
