SEATTLE — Hundreds of thousands of notoriously loud Seahawks fans cranked up the volume Wednesday, cheering, chanting and going berserk during a parade and ceremony to celebrate the first Super Bowl victory in the history of the franchise. The mood in Seattle was electrified as the parade featuring the NFL champions began near the Space Needle and made its way to CenturyLink Field, the home of the team. At a ceremony inside the stadium, the team thanked its loyal followers — the 12th Man — capping a day of boisterous celebration that drew an estimated 700,000 revelers to Seattle.
