It takes two teams to play Aussie Rules football, but you need a third team -- the umpires -- to actually play a match.  Exuding a passion for the sport and a "spirit d'corps" attitude, the USAFL Umpires Association has been an important cog in the growth of the game her in the USA.  Members of the UA have become AFL accredited and have gone on to umpire matches all around the world, including in Australia.  To chat about the history of umpiring here in the US is Steve Arnott, who has umpired several hundred games since joining the league in 1999.
