The authorities in Nevada are getting concerned about travelers relying too much on GPS devices. From MSNBC.

Had that happen to me once in NH in early spring when my GPS sent me on a back road with 12 inches of slush. Fortuneatly I was driving my AWD Subaru and got through with just white knuckles. The main road I turned off of was clear and dry.
