Go to the projects in Baltimore.
The Smithsonian (specifically the Air & Space portion) was awesome. Lots of history in there if you're into that sort of thing. Also, parking is all over the place and free if I remember correctly.
Big fan of the Serial Podcast? You can tour of all the sites including Leakin Park. Its all just west of Baltimore.
To go to DC from Baltimore I would probably take the MARC train to DC. http://mta.maryland.gov/marc-train
Traffic in the DC-MD-VA area is the worst in the country, yes even worse than LA.

If you haven't already completed your Christmas shopping, you could stop by the National Cryptologic Museum and pick up this year's NSA Christmas ornament.From Thursday to Sunday in 2 weeks
I would like to go sight seeing in washington D.C. Please help me make the best of this trip. Thanks
Not a place that everyone would enjoy, but for those interested it can be fascinating...The NCM collection contains thousands of artifacts, including numerous working World War II German Enigma machines (2 of them are available for visitors to try out), and a Navy Bombe used to break it. Displays discuss the history of American cryptology and the people, machines, techniques, and locations concerned. Initially housing NSA artifacts for viewing by employees, the museum quickly developed into a collection of U.S. cryptologic history, with some artifacts dating back to pre-American Revolutionary War times.
In addition to exhibits covering equipment used to encrypt, decrypt, and secure information, the museum features exhibits on the people who contributed to cryptography in America, such as George Washington (who integrated military intelligence tactics, including coded messaging, into the Continental Army during the Revolutionary War), the Native American code talkers (who protected U.S. communications during both World Wars by using their native languages to encode message traffic), and the Navy WAVES (who, like the WRENS of the British Royal Navy, operated the Bombe to decrypt German military traffic during WWII).
since you'll be in Baltimore to start with, def check out the Baltimore National Aquarium ... one of the best Aquariums in the US IMHO and is well worth it (despite what the other poster said). shop around for tickets, you can find them for cheap
after that you can either take a MARC train to DC, or rent a car and drive... plan on getting to DC early and staying all day, and check out all the museums that surround the mall. if possible, I would even try to stay in DC one night, so you have ample time to checkout all the museums (if you have to pick and choose, National History and National Air and Space are the two you cannot miss)
I have to travel for work but i am using 2 days for vacation and leave sunday.. Is there a train to go to DC? I would like to see DC.
yes there is a Metro but not sure where it ends in relation to Baltimore. I would take the metro otherwise you will spend all your time driving around D.C. looking for a place to park
