ETT Season 4, episode 10: In this episode of Every Third Thursday, Signal Snowboards teams up with the Unknown Industries Harley stunt biking crew to collaborate on custom snowboard motorcycle racks and snowboards. The Unknown crew including Nick Leonetti, Buddy Suttle, and Kade Gates rally with ETT host Dave Lee to Bear Mountain to try out the new racks and the new boards. It's possible that they do more tricks on their bikes on the way up to Bear Mountain than on their boards coming down — it's all about wheelies, burnouts, and boardslides in this episode of ETT!
