The atmosphere of this day in U.S. capital is especially festive and solemn. The official ceremony takes place around noon on the West Lawn of the U.S. Capitol when the vice president-elect and president-elect take the Oaths of Office. This ceremony requires a ticket, which is free and can be obtained through congressmen or senators' offices. If you don't have a ticket you can watch the whole thing on a giant video screen on the National Mall with thousands of spectators. You can also go to Pennsylvania Avenue to watch the presidential procession and inaugural parade passing by when they leave the U.S. Capitol and head to the White House.
