For so many in the mountains, skiing is life. That is certainly the case with the allegorical main character in Winter’s Wind. Based on the legendary ski bum Gary Bigham, who lives in Chamonix, France, this unusual film shows how rich life can be — even if all you really have is boots, skis, poles and a boundless desire to point them downhill. The director, Matty “Moo” Herriger, has worked as a cameraman with some of the big names in ski films — such as TGR and Warren Miller — but after several decades of shooting for other directors, he’s made his own project of passion about the sport.
