Peppering New Hampshire, and especially Manchester, are activists and candidate supporters standing in the cold with street signs. Here's a time-lapse look at what it's like to wave a street corner sign from ABC cameraman Jim Sicile.

Voting started at 6 a.m. ET and candidates tried to visit voting locations to drum up last minute support. The most heavily visited location was at an elementary school in Manchester's Ward 1.

Republican candidates including Newt Gingrich, Mitt Romney and John Huntsman were engulfed by an army of cameras and reporters today.

Two reporters were pushed to the ground in what can best be described as a mob scene at the Webster school in Manchester.

Gingrich, the first candidate to visit the location, likened the scene to Mardi Gras "without the alcohol, the fun, the excitement."

"But other than that, it was certainly as crowded as Mardi Gras," he told reporters on his campaign bus. "And it was weird because the crowd moved.  It was like you had this moving amoeba."

The former speaker's wife, Callista, said she had never seen anything like that.

"No one was really in control of the sheer volume of people," she said.

Jon Huntsman was supposed to chat with reporters but it turned into a free for all as cameras jumped the barricades to get to the former Utah governor.

Even police officers on hand were unable to control the crowd. As he jumped back into his car, waved at supporters and left, police officers attempted to clear the press, yelling, "Get out of the street. He's gone."

Here's a look at Huntsman in the media crush.

While the outside of a voting locations can be surrounded by reporters and canvassers, inside is a campaign-free zone.

A literal wall of mostly Mitt Romney's supporters chanted "We Want Mitt" as voters entered the polling site.

Romney also visited the polling site this morning. His security team put a tight perimeter around him and his wife, Ann, amid concern about the crush.

The former Massachusetts governor arrived in his campaign bus and walked up to the supporters near the door, shook hands, and turned back around.

Romney said he hopes that he does well and that if he gets "double the number of vote margins that we had in Iowa, I'd feel terrific."

"I hope the people of New Hampshire turn out," he added. "The entire nation is watching."

As he was holding a baby, Romney was heckled by the crowd, with someone asking him if he would fire the baby.

Rick Santorum was also scheduled to attend but his campaign said they changed plans when they saw "the mob."

He talked to ABC's Jake Tapper instead.

While the media circus trampled above, ABC's Susan Archer spotted this sidewalk art supporting Ron Paul underfoot:
