Last week I told you about my geek tip for remembering where you parked in a huge parking structure [1] or mall lot by taking a pic with your cell phone's camera, but needing to know where you parked isn't confined to being in a parking lot. Have you ever tried to park in a big city, for instance?

I happen to live in a very busy neighborhood where parking places are scarce. Once you find a place to park your car, you're pretty far away from your destination. Before leaving your car in no man's land, snap a picture of the street signs (preferably the intersection) with your cell phone's camera.

Check it on your way back, and forget about wandering the streets like some sad, lost tourist.
