Photographers inspect a giant 40x40 foot planning map used to help organize Barack Obama's presidential inauguration on Jan. 20th, 2009. Up to 4 million people are expected to flood the center of Washington, DC -- which would be a record. The record now is 1.2 million, for Lyndon B. Johnson's inauguration in 1965. About 100,000 people came to witness George W. Bush's second ceremony in 2005.
