The two things that continue to amaze me every week are:
(1) Teams that do not read the clues in detail.
(2) Teams that are incapable of reading a map.
I realize there's probably a lot of adrenaline pumping and teams are just trying to move as quickly as possible, but the amount of time that teams are losing not doing the above is blowing my mind. When Jet and Dave kept re-filling the coal cart last night thinking that was the problem, I wanted to scream! And the girls asking for directions and then STILL not having any idea where they were going? AAARRRRGGGHHHH!!!!!
