It would be impossible to fathom the emotional roller coaster that Rachel and Dave went on toward the end of "The Amazing Race" (Sun., 8 p.m. ET on CBS). They were looking to set a new record for legs won by taking their eight leg, and the million dollars. And they hit the finish line to the cheering of the eliminated contestants. However... What a terrible time to find out that they'd missed a Roadblock! Even more shocking was when they went back to do it, Rachel quickly flew past Art on a Hawaiian sled and then just as quickly finished up the task.
