I wait for my last connecting bus in the morning, in a sort of five-lane-wide tunnel under a building. Today, I was nearly deafened in this somewhat enclosed space by sirens and loud sonic bursts (accompanied by red, white, and blue light bursts) from first one, then a series of police motorcycles. A limo came past, then a few more limos, then three Bauer buses with opaque windows. I've watched West Wing -- was this the presidential motorcade, complete with staffers and reporters in those Bauer buses? The motorcade headed onto the freeway and out of site, and my bus arrived and I rode to work.
