Terrafirma 4’s riding offering stretches far and wide, from silky smooth sessions in the hills of California with Jeremy McGrath & Kevin Windham, mind-bending off-road “sends” in the Canadian wilderness with Guy Perrett, freeriding in Chile with Edgar Torronteras & Andy Bowyer and everything else in between. The series really started to expand into different types of riding in this installment and also includes Trials competition in Donner Pass, California, Hill Climb racing in Billings Montana, and the freeride cross-over of big mountain snowboard legend, Mike “Tex” Devenport.
