"Amazing Race" host Phil Keoghan really wants to do an "Amazing Race" reunion. I mention this, because in the two times I've talked to Keoghan in the past couple years, that is the only repeated point. "Survivor" has reunions after each season and Keoghan would like "The Amazing Race" to follow suit. Keoghan and I got on the phone last week to discuss the upcoming conclusion to "The Amazing Race: All-Stars," a season that is heading towards its conclusion on Sunday (May 18) night with Jen & Caroline, Brendon & Rachel and Dave & Connor still in the running for the big prize. We talked about the biggest story lines surrounding each of the remaining teams. Is Dave's quest to become the oldest "Amazing Race" winner a notable one? Are Brendon & Rachel capable of actually being underdogs? And should we be dismissive of the Country Blondes because of the amount of assistance they've gotten from other teams?
