Unlike, say NYC or Chicago, you won't find a subway stop every couple of blocks in the Washington area; instead, DC's subway was built on a "hub and spoke" system. It's great for moving ppl into the center of the city, but not necessarily for getting from point A to point B outside of that central area.
One of the results of that design is that the Washington subway system is, on average, a bit less...um...colorful than some other big-city subway systems. For the most part, my fellow passengers during the morning rush hour are also your professional 9-5ers, all heading into their offices for the day. On average, it's pretty quiet in the subway car, as ppl tend to doze, read the paper or a book, do a crossword puzzle, etc.
Then there are days like this morning. There were delays on the line, which meant the car was much more crowded than normal. Then, a (most likely mentally-unstable) woman got on, lugging a cartload of stuff with her, which wouldn't be much appreciated on a regular rush hour, but was even less so given the overly crowded conditions. She started telling everyone w/in earshot how she had taught herself to play multiple musical instruments, never had a lesson, etc. She then decided to show us with a little performance.
Let's just say, you haven't lived until you've heard both the US Marine Corps anthem ("from the halls of Montezuma....") and the Star Spangled Banner played on the harmonica in the middle of a crowded subway car during your rush hour commute.
Let's hope tomorrow's commute goes back to being quiet & not very colorful.
