Honestly, what were we going to pick here? KeyArena? That’s cute. Safeco? Sure, maybe, if the Red Sox are in town and the place is actually filled past half capacity. The obvious choice is CenturyLink Field, or The Clink, as it’s been affectionately nicknamed. Home to 67,000 slobbering Seahawks fans on fall Sundays, CenturyLink is one of the NFL’s most intimidating venues, thanks to the incessant drunken roar of the 12th Man. But the legion that’s really lifted CenturyLink to the next level has been the scarved Seattle soccer fans who arrive en masse to cheer on their beloved Sounders at every available chance and have succeeded in creating an atmosphere unmatched in the annals of U.S. pro soccer. Even during the occasional nil-nil futbol snooze-fests, the fans at CenturyLink keep things entertaining.
