A little local note.
The DC Circulator began operations today, and I think we have a winner here. It is essentially a simplified (no route numbers; two routes, intersecting at the Convention Center; flat $1 fare) and upscale (clean, airy, low-floor buses) bus route that should help tourists, intown workers, and folks like Hubby and me who live pretty close to downtown. We're now tied in better to Union Station (railroad), Georgetown (shopping), and the literally fishy (waterfront restaurants and market) part of Southwest DC. (The vegetarian thing isn't going to plan.)
Plus it is free this week.
