Not a bad show at all... way better than most of the moto-related stuff we get on TV. I think its aimed at the casual rider and shows how difficult and dangerous some of this type of riding can be. Navigating those twisty two lane roads in Peru with all the truck traffic ain't exactly safe from what I saw. I've got my DVR set to record the whole series.
And the doctor... yes, some very nice assets all around, especially in the garage (Lotus Elise, Porsche, Ferrari, etc). Business must be good!
