I've got no sense of direction. Zero. I can get lost in my own office or go the wrong way down a street I've been down 100 times.

Still, I've noticed that because I bike and walk around when I can I'm much more able to get around San Francisco than most of my friends. You just use a much larger and more generalizable set of "clues" to get around. When you use GPS there's no decision making so you never really learn why you turned on Street X not Street Y.
