U.S. Army combat pilot Dave Brown and his wife Rachel have won Season 20 of "The Amazing Race." They traveled nearly 40,000 miles across five continents and 22 cities to win the $1 million prize. On Sunday's 2-hour season finale, they beat out their fellow finalists in challenges that took them to India and Japan. The others who made up the final four teams were engaged former "Big Brother" contestants Brendon Villegas and Rachel Reilly; boyfriend-girlfriend Ralph Kelley and Vanessa Macias; and Art Velez and J.J. Carrell, who are Border Patrol agents and friends. Phil Keoghan is the show's host.
