I've jusr watched the latest episode of the amazing Race Asia 3.
I tell you what, if you guys have access to torrent, you should have a look at TAR Asia. I've seen all three seasons now, and the second one I thought was tough, but this season is much tougher.
These guys are put through a LOT more strain than their US counterparts. They stuff a lot more stuff in each leg, the legs are gruelling.
its quite interesting becasue in TAR Asia there is a lot more nationalities. As its for the whole of Asia. So Japan, India, Thiland, Manilla, Hong Kong, Phillipeans etc etc are all represented.
