It seems that the walls in the Embarcadero station are actually <em>white</em>! Who knew? I'm glad to hear that they're finally getting a thorough cleaning. I hope this doesn't stop with Embarcadero: it'd be great to see all the other stations similarly cleaned up. And I'm glad to hear that that ugly overgrown macramé thing at the end of the platform has been dumped.
