I have an absolutely terrible sense of direction, sometimes I wonder if its some kind of mental disability I have, and i'm not even kidding.
I get lost a lot. It takes me a long time to memorize a place (in the town I LIVED in it took me a couple of years before I felt like I comfortably knew where things were). I even get lost in games sometimes, and i'm talking the most linear one-way FPS games even.
