Ugh! Bah! Humbug!

Some people might think it's fun, but let's look at the other side of it. WMAL radio's Bill Trumbull and Chris Core are sponsoring the lighthearted first annual Gross National Parade, a kind of Mardi Gras event, through Georgetown tomorrow. It'll block M Street and mess up Metrobus service terribly. In fact, you won't even be able to get from Virginia to central Georgetown by transit (or, for that matter, by car) during the parade hours, 3 to 5 p.m.

Oh, well, one suspects that those in the parade or watching it will have fun. There will be, for example, a briefcase drill team and a team disguised as Frank Perdue's finest chicken breasts.

It's all for one of the best of causes, raising funds to renovate and reopen the Anthony Bowen YMCA.

Now for the bread-and-butter information for Metrobus users: The 30-series buses serving Wisconsin Avenue will operate between 3 and 5 p.m. over P Street westbound and Q Street eastbound between 22d or 23d Street, depending upon direction, and Wisconsin Avenue. The 38-B (Arlington/Key Bridge) buses, normally the only link between Georgetown and Arlington, will skip Georgetown entirely, operating via the Whitehurst Freeway. Best advice to route 38 riders is to take the subway; it's far cheaper, anyway.
