Sigh, I knew it. I accidentally read spoilers that said that in the 5th or 6th leg R/A weren't seen anywhere and I hoped that it would have been a case like when they did those books in their first leg when they were soooooooo ahead of the pack, but alas, no. And all of the previews made it pretty clear that yeah, it was the end of the road. It was partially bad luck (not finding it) and the way the leg was spread out with very little bunching, but they DID screw up the first task by not checking the spelling of the places, had they done that right away, they would have been in 3rd place after that first task.
Ah well. They were wonderful to the end though, and had such a great attitude. I loved them. I just hate that frickin' Charla and Mirna beat them. I'm rooting for Danny/Oswald and Terri/Ian now, but my love and enthusiasm for this season is gone with Rob and Amber. Sigh.
