You sort of have to (safely) weave in and out between these to get to your meetings and events or hop on one to get there, perhaps, more quickly and enjoyably.
Anyway, as you can tell, D.C., like many a big city (ah, reminds me of the Big Apple) has many a colorful characters in the downtown.
It adds to the charm--sometimes--and can make for a nuisance at others.
But, it's never quite boring.
Hope this gives a good flavor of what's like to work, and play, in The Capital. ;-)
