I get too easily lost. When going from one place to another that requires turns, I will more than often take note of landmarks along the way — notable stores, odd looking lamp posts, even the occasional fire hydrant that has interesting graffiti on it.
I know when I pass a particular store, I am going in the right direction. I have often wondered how people do this kind of thing when climbing mountains. I figured that perhaps they use flags that have been planted by successful climbers in the past. It turns out that I was somewhat right, except about the part of the climbers being successful.
