WASHINGTON (CNN) - Hundreds of thousands of Americans are planning to converge on the National Mall to witness the historic moment when Barack Obama takes the oath of office and becomes the nation's first African-American president.
But if they plan to share pictures or video of the moment Obama utters "so help me God," with friends and family using their mobile phones, they may have to wait.
And wait... and wait... and wait.
The cell systems around the National Mall will be overloaded if the expected record crowds actually materialize, according to a spokesman for CTIA, the association representing wireless carriers. All those phone calls, texts, picture and video messages will hit a log jam.
"It'll be like everyone leaving the beach at the same time after the Fourth of July," said Joe Farren. "All roads will come to a standstill."
