"Not quite GPS, but I had a MapPoint map that instead of telling me to turn left, turn right, and drive right into the ocean, being on the east coast of Florida.  The sad thing was, yes, I could have turned right onto the beach and kept going.  I decided to turn left to my desired destination. Recently, my daughter-in-law moved, and in trying to get to her new apartment, my Garmin wanted me to jump from the road I was on up to the overpass to get to there.  We got there, a half-hour late..." - Bryan Price
