CNN's Ashley Killough spoke to Carlos Arieta, a police officer from Atlanta, who was originally scheduled to come work security for the inauguration but found out he was no longer needed:
So he and his wife Sharon, a nurse, decided at the last minute last week to make the drive from Georgia and come to "enjoy as spectators."
"This is history in the making," Sharon said, noting that the second inauguration of the country's first black president falls on Martin Luther King Jr Day.
While they're both former DC-area residents, this is their first inauguration and they say they're surprised to see the throngs of people crowding the Mall.
"But it's nice to see all the different kinds of people," Carlos added, with a look of satisfaction on his face.
