"Simon Dumont's Cube Pipe at Squaw Valley, Calif., was a really complicated and technical build. I loved that project because in each of the cutouts you can see just how big a 22-foot pipe really is," Gunnarson says. "And when Simon came back after the cubes were cut in, he had no chance for warm-up. It was just nail it and don't come up short."
