Whitey,
Sorry for not being more specific…thanks for sharing the videos though, quite informative. I do not actually live in the ski town (above 7,000ft). I live about an hour south in a town situated around 4,000ft in elevation. Winter hits the Sierra hard here, but snow rarely accumulates/sticks to the ground here in my town. Most of my driving to the resort town will be when the roads are clear, but there will be an occasional day when I wish to head up after a storm for powder skiing. Hence I am seeking chains or cables, at least for just this winter.
