The Amazing Race Season 17 Episode 4 airs at 8 p.m. tonight, Oct. 17, 2010, on CBS.
Two teams have already been eliminated: best friends Ron and Tony and birth mom and daughter Andie and Jenna. Father/son team Michael and Kevin almost had their dreams dashed last episode, though it was a non-elimination leg of the race and they'll be in tonight's episode.
The teams started in Massachusetts before they flew to England. From there, they made their way to the African nation of Ghana. In this leg, they're expected to fly to Sweden.
