Washington D.C.

/
White House The capital that has the Capitol. There are many museums i.e. Art, Air & Space, Natutal History, etc. here and they are all free. I had been in D.C. two times but I still couldn't visit all. If you want to visit all museum, prepare to stay there for at least a week. Eventhough, the parking space is rare and expensive, D.C. has a nice, clean ,and very convenient subway system.
You can take subway to almost every tourist attractions in D.C. or go shopping and having something to eat at the Union station. After visiting all important and beautiful official buildings in D.C. we can have Thai food in Virginia side. Anyhow, there are some specific place you should not go at night. Capitol
