I honestly don't know why, but we love this show.
Neither of us knows how to drive a truck (or even stick shift)...
We both hate snow and cold...
Neither of us has any particular love of or for trucks, truckers, or the profession of truck driving.
But we love the show nonetheless.
Most of the show, we look at the screen and say something like, "Tsk tsk that is one crazy dude" (although this year, they have a female driver). We also like to critique the cgi truck crashes.
