So far in Sweetgrass Productions’ “On the Road” series, there has been an excess of what could accurately be described as masochism–dust storms, frostbite, dental emergencies, gastric turmoil, avalanches, shitty snow–to accompany the adventures. Not so for their 10th episode, where the crew lavishes at one of South America’s finest resorts, Hotel Portillo.Wine, women and powder abound, and–for at least a few days–life seems pretty sweet.
