At World Cup 2010 in South Africa it was the buzz of vuvuzelas. Soccer now has its own unique sound track in the U.S.: the singing and chanting of the American Outlaws, who helped boost the U.S. national team to five shutout wins in five home qualifiers this year. Launched six years ago in Lincoln, Neb., in an effort to unite like-minded fans at bars and stadiums, AO has blossomed into a national network of more than 15,000 diehards. The grassroots outfit has already booked three charter flights with 516 members to the World Cup in Brazil (there's a waiting list of around 2,000), and half of its chapters were present at last Friday's 2--0 win over Jamaica in Kansas City. Among them was the 100th, Wichita, which was inducted on the eve of the game. Most chapters have a logo and the best represent a commitment to cause, community and country. Here are SI's favorites.
