Buses: Reliable Transportation?

There are many ways to get around D.C. When it is raining and I am going more than a mile I prefer to take the bus. Today I took the bus to the Corcoran Campus H St Library and applied for a variety of photographic internships and summer jobs. Aside from that I did two favors that both involved photography. I am also researching the pros and cons of joining the Army National Guard. I just wish there were no such thing as the Nazi ... I mean Patriot Act. If I get an internship, chances are I'll need reliable transportation. If I join the military, they provide the transportation ... but to where?
