The Great GPS disaster on New Year's Eve

On New Year's Eve we were invited to a party at a friend's cabin in Twain Harte, CA.  We used our GPS to get to the party and ended up heading higher into the icy roads of the mountains getting farther away from our destination!  Our friend's husband ended up rescuing us at the Confidence Inn off 108.  Yes, this place really does exist!  A good old fashioned map of the area would have been more helpful.  When the white truck saved us at the Confidence Inn, I felt I could breathe again!
