Traveling to Washington, the capital of the United States, at night, by local, former colleagues who worked together drove us around, to Georgetown, a very famous old city, it is Washington's neighbor, from the heart of Washington, to come here at night without traffic jams, About 15-20 minutes. There are many old houses on both sides of the street here, all of which are houses in the old era. At that time, Christmas was approaching, and Christmas decorations were hung at the door of many big houses. The lights were beautiful at night.
