When my Keep Walking South system was becoming unworkable, I decided to try this system closer to home. It's inspired many walks, and overall been a good thing. I've done this enough such that I've "used up" San Francisco's geocaches. (People are planting new ones all the time of course; I don't try to visit those, since they won't be near any other new caches.) Lately, these walks have started about 12km from my apartment building.
Sometimes I balk, though. I skipped Treasure Island (incorrectly thinking it made sense to wait until the new Bay Bridge's pedestrian path connected it to Oakland) and Alcatraz. I walked around Angel Island when the system told me to…but it took me a couple of months to get around to that walk; this game tends to go on hiatus when it gets inconvenient. Still, it gets me out from behind the computer; most recently it got me to walk on the new Bay Bridge and wander a bit in West Oakland, including a free library shelf built into the side of an old warehouse.
