@Dscholfield - Honestly, I'd probably stop skiing if I didn't have the driver/friend interaction that having a cable system eliminates. If I can't get/give shit-talk (ok, or coaching for that matter) while sitting at the end of the lake waiting for my next pass, what's the point? It's not always about your actual passes but about the lifestyle. I suspect the social interaction will strongly limit the popularity of that kind of system.
