The sleuths at Reality Fan Forum have kept up their identification of Amazing Race 17 teams. Earlier, when the season was still taping (it ended production in mid-June), the site identified four beauty queens but then retracted two.
They’ve now added another beauty queen (warning: spoilers). She’s Miss Oregon 2004 Brook Roberts. They also have information about how these and other teams did, so if you want to be spoiled about locations and eliminations, read this discussion thread.
