Yet another reason I'm so glad I don't have a car! (And in Berlin with the public transit you don't need one.) It's interesting how this little board is evidence of nightmarish parking conditions (and stressed-out forgetful minds?)...although Berlin has a lot more parking than other cities of this size. Anyways, I thought this was brilliant!
I thought of a certain friend of mine who could use this...except she forgets where she parked on campus, so she would need a work-centered map rather than home. :)
