I actually saw the sun set in the east, 7 years ago. I got off the train in Grindelwald, Switzerland and started to navigate my way up the hill to the youth hostel. I looked at the rather sketchy map from the hostel website, looked at my little zipper-pull compass and then looked at the sun and thought "what the...." There must have been some kind of power surge in the electric train that reversed the polarity of my little zipper-pull compass. The rest of my Europe trip was an interesting exercise in navigating with a reversed compass (south is north and west is east and northwest is ???). I almost got lost while hiking in France's Cevennes.

Moral: believe the sun before you believe your compass.
