In this episode of Every Third Thursday, Dave Lee and the entire Signal Snowboard factory crew team up on a huge project—a 10-foot long (304 cm) snowboard. The whole factory needs to be rearranged to create this behemoth board, but it pays off in the end. The board is mounted on top of the 4Runner and the crew arrives just in time for opening day at Mammoth Mountain.
