»In which we have more adventures with MUNI

Last night, Anna and I were returning from a film and a walk at the Embarcadero when we decided to take MUNI back home. Nothing could be simpler, right? At the Ferry Terminal, the eastern edge of San Francisco, a half-dozen light-rail lines (and the F-Market historical streetcar, to boot).

The light-rail stops running after ten o'clock due to ongoing track work, but that's no problem: MUNI runs shuttle buses.
However, the surface buses skip the Financial District entirely, and the 71 first alights at Fourth. So we walked a few blocks, hedging our bets that the F would not show before we got to Fourth. And it didn't. Neither did the 71, though, and that's what burned us. We waited for more than half an hour.
