Where are you?

The Bay is the water between SF and Oakland — its eastern waterfront, not the ocean or Golden Gate side. Which way is one of eight compass points from your facing — front, front-right, right, back-right, and so on — and you can set it even under “Can’t see it,” since you usually know a landmark is off to your left even when a hill or building hides it. Near / Far is a few blocks vs across town. Tower visibility is a heuristic, so read the result as neighborhoods, not a GPS pin.
