Douglas Hofstadter, somewhere in his big book about translation, talks about a game he played as a young'n, called "Leftmost Rightmost." You walk (or drive, or ride) down the street till you reach an intersection. You take, alternately, the leftmost then the rightmost option. (Sometimes straight might be "right," because it's your "most" right option.) That's it. It provides surprisingly satisfying randomness.

I play this game looking for locations. I like best: hotels, hospitals, malls, community centers, construction sites, buildings under renovation or asbestos abatement, office buildings, churches, city halls, cemeteries, libraries, airports, box stores, public buildings of any sort, parkades, and abandoned buildings. Especially hotels.
