How much fun would it be to tango through the streets of Buenos Aires?! You can live vicariously through the Delta SiteSeer Challengewhich is sending three teams there. One team was already eliminated in Budapest. Through friends we've met John Crow from Team Steph & Crow On the Goso we are voting for them. You can vote too and earn 250 miles for each round (if you register and watch the videos). Voting for the Argentine round starts August 20.
