I did it once (I was stranded out in the country in the middle of winter) and I was terrified. I'd never do it again unless my life was in danger. The people that picked me up were very nice (two farmers on their way in to town) but that doesn't mean I wasn't saying my prayers the whole way into town.

As it turns out, they recognized me from the farm store I worked at. I didn't know them, though.
