ETT Season 4, episode 3: Signal Snowboard’s Dave Lee builds two experimental snowboards at the Signal Factory with the goal of riding epic sand dunes in a world without snow. One board features an ABS plastic base and the other a Formica base, both with the goal of overcoming the challenge of speed on sand. The setting for the test is California’s Glamis Dunes, a motorsports recreational mecca with steep mountainous dunes. The test has a sticky outcome, which leads to a new world compromise—enter Professional off road racer Rob MacCachren and his off road trophy truck! Snowboarders Spencer Link and Nick Sibayan get the ride of their lives behind Rob’s truck to see if, with a little help, they can get the same effect on sand as on snow. Looks like the driver might be getting more face shots than the riders in this episode of ETT. Back to the drawing board! What new base materials do you think would work to get this board sliding on sand?
