Over-engineered Walks a year later: Munzee
I still play Munzee, in which folks post the GPS coordinates of barcode stickers, and I go find and scan those bar codes. Since you only get credit for scanning any particular Munzee once, it gives me an excuse to visit new places. On Sundays when another system suggests that I walk someplace with slow Sunday bus service, I'm likely to head out in search of some Munzees instead.
