In f/u to Snow Chains for the Sierra: I see from the ODY manual I need "SAE class S cable type traction devices." Whew. I live in Massachusetts, where chains don't appear to be sold. (Having moved here from Reno, I can't quite fathom it, but on second thought, no one can drive more than 30mph here anyway.) And since I am driving back to Reno shortly, I want to buy regionally (NE)and go over installation carefully, since a snowstorm in Wyoming is no place to find out they don't fit. Would anybody in the NE region have any suggestions for me as to a local source for cables? NH? Vermont? Even Eastern upstate NY? The spikes-spider are pricey and apparently mail order only for me.
