NYT: The advisory says that ticket-holders should arrive at least three hours before the ceremony begins at 11:30. The place will be jammed. Streets will be closed and so probably will the bridges and major roadways into the district, unless you’re on a special bus. If you’re already staying within two miles of the Capitol, you should walk to the swearing-in. If you have special needs (like, you can’t walk), you’ll still have to walk, or use a wheelchair.
There will be “drop-off” points for people with disabilities, but “traffic conditions and restrictions may make reaching these drop-off locations extremely difficult.”
If you’re coming by Metro: “Be prepared to wait for space on a train for long periods of time, during which you will have to stand in close proximity to several thousand people. Many Metro escalators will be closed due to crowding and individuals will need to climb Metro stairs or wait to utilize the small number of elevators at Metro stations.”
If it’s raining? You can’t get through security with an umbrella. Bring a hat or poncho.
And if you’re on medication, like insulin, that you need to take at regular intervals, bring it with you. You’ll be there for many hours.
First Read also has some advice:
Be in line by 9 a.m., but don't bring your umbrella, even if it's raining.
That's the advice from the congressional committee responsible for the formal portion of the Jan. 20th inauguration.
The swearing-in program will begin at 11:30 a.m., so that the oath of office can be administered to Barack Obama at noon, as the Constitution requires.
Security checkpoints for ticketed guests open at 8 a.m., and the committee recommends that ticket holders arrive no later than 9 a.m. to get through screening.
