Just as speculated, the Amazing Race All-Stars edition filming is just underway. Foremer racers were spotted at the Miami airport on Monday the 20th of November and said they were headed to Quito, Ecuador. Several teams were spotted confirming rumors such as Rob & Amber, Charla & Mirna, and Bill & Joe (Guidos). Other possible teams on the race are Dustin & Kandace from the current season, Jon Vito & Jill and possibly Blake & Paige. Stay tuned for more spoilers and updates as the race continues!
UPDATED 11.29.06: More sightings! Yesterday (the 28th) the Guidos were spotted in Ushuaia, Argentina in an internet cafe looking for flights to what appears to be South Africa. Ushuaia is called the southern most in the world and is used as a launching point for trips to Antartica. The Antartica mention is just speculation but I had to add it since I've been waiting for years for this to become a true 7 continent race. More updates and spoilers certainly to come!
