Lumen Field (the '12th Man' noise gag)

Lumen Field, at the site formerly called CenturyLink Field, is the home stadium of the NFL's Seattle Seahawks and MLS's Seattle Sounders FC. The stadium is widely known for its very loud home crowds and the Seahawks' '12th Man' fan tradition. Opposing teams have been penalized for false starts attributed to crowd noise, and locals commonly joke about the stadium being so loud it affects the rest of the city.
