I'll go into a building knowing the office I'm looking for is on the north side. Turn a few corners, out of site of the windows, take an elevator, come out in another hall with no windows ... now which way am I facing again?

Coming out of a parking garage, exit is nowhere near the entrance, down seven levels of corkscrew ramp ... what road did I just exit on?

Few of the streets in East Cleveland go straight more than a couple of blocks. Similar to Boston, but for a different reason. I got turned around there after dark once. Not pleasant.

So yeah, I think this would be cool.

I've got a pretty decent mental map of the city. It's when I walk out of a building through a door I don't use often, and I'm not sure which way I'm facing, that it gets tricky.
