That's cause Amazing Race IS interesting (IMHO). It's one of the 3 reality shows I actually watch & like (Survivor & American Idol being the other two).
You really have to wonder what dim bulb decided to select a couple of fat 40-somethings for the Amazing Race, and then have them march up and down the side of a mountain or two. Did they actually expect them to be competitive, or were they simply meant all along to be "first show fodder?"
