I ran the search from DC to Harrisburg, and got a blank result.
Dulles to Falls Church is about 30 minutes or so (I lived for 3 years in West Falls Church). The subway might be tough to navigate, though, if you have luggage - you have to get on one train line, and then change to another, to end up in Union Station.
Another question: I have moldovan driver lincense. Will I be able to drive, or in US is valid only us driver lincence? If i need US driver lincense, can I take the test to get a DL? OR it is restricted for students that come to US at summer?
At lest in Calfornia, you officially have 10 days to go to the DMV and start the paperwork. First you take the written exam and if you pass they give you a paper that you can drive for 3 months (while you get an appointment for the test drive). That is officially, unofficially I was like a year and a half with my Argentinean DL (though I had to always have my Argie passport with my VISA). I got pulled over a couple of times and they didn't care that much.
If you are going to stay for a couple of months I don't think you need a DL. My company used to give me a rental car during that year, with an insurance under my Argie DL.
i suggest you to get an international driver license before you arrived in USA.
depends from State to State, but after "911", driver licenses rules changed a lot: most of the States now they gave you a Driver License after you do both written and drive test for the lenght of your visa. If you have a tourist visa, that will be 3 months. They used to give you the DL right after the test, but now you receive it by mail 3-4 weeks later, so you need to have a valid address, in some states (Connecticut for example) you need a prove of address by providing a copy of a bill with your name on it.
i hated those circles in Europe when i lived in Italy, and now i remember why i hate those so much.
Dupont circle is just a nightmare, i still can't understand GWU circle; those are suppose to make traffic better, but the way they are set up, it make it just impossible. If you need to put red lights into the circle, why don't do a regular cross. like everywhere else in US.
I used to go down there back in the day before GPS, and all I had was a paper map on my lap and no way of knowing what streets were one-way, and really no possible way of getting anywhere I wanted to go.
One time I just pulled over and started screaming, I was literally ready to kill somebody.
My gf is a courier down there and always brags about being such a badass and knowing all the shortcuts. Typical obnoxious DC driver.
