SEATTLE (AP) -- Hundreds of thousands of notoriously loud Seattle Seahawks fans cranked up the volume on Wednesday, cheering, chanting and going berserk during a parade celebrating the team's first Super Bowl victory.
Police estimated about 700,000 people -- more than the population of the city -- attended what might have been the largest gathering in Seattle history.
The parade began near the Space Needle and slowly made its way to CenturyLink Field, the home of the NFL team.
Dakota Heaphy, 20, who called himself a lifelong Seahawks fan, and friend Ellie Hergert, 20, drove all night from Cheyenne, Wyoming -- more than 1,400 miles (2,200 kilometers) away.
"My boss is a Broncos fan and said we kicked their butts and deserved to go," Hergert said.
Revelers packed the two-mile (three-kilometer) route and greeted the team at CenturyLink Field and nearby Safeco Field. They wore blue and green wigs, waved flags, scarves and signs, and erupted into song and dance.
The Washington National Guard chauffeured many of the players in Humvees and other military vehicles under blue, sunny skies in cold temperatures. Elected officials rode along in amphibious vehicles used to take tourists around the city.
Players enjoyed the celebration as much as the fans.
Running back Marshawn Lynch sat on the hood of a vehicle carrying the Sea Gals cheerleaders. He tossed Skittles -- his favorite treat -- into the crowd.
Other Seahawks players threw jerseys and T-shirts to fans while waving blue "12" flags as a sign of gratitude to the loyal fans, known as the team's 12th man.
Boisterous fans observed a "moment of loudness" at 12:12 p.m. Crowds also gathered in Spokane and Olympia to celebrate the first championship in the 38-year history of the franchise.
Many fans camped out overnight to reserve front-row seats along the route, braving freezing temperatures. Others perched on window sills and balconies, climbed trees and pillars, or sat on sturdier shoulders to get a better view.
Bubba Lezard, 28, said his Muckleshoot Indian Tribe, gave everyone the day off in honor of the Super Bowl champions. He, his wife and six-month-old baby traveled 1 1/2 hours into Seattle for the parade.
Paul Szabo of Shoreline also pulled his two kids out if school to attend.
"The teachers are probably jealous," he said. "If I was them I would have canceled school."
