I agree with Colin, I don't like this system either. It's all been reduced to just be in the right place at the right time, which removes most of the challenge. I was also mad that this leg (of all legs) was used as a tryout. With the exception of the lattitude/longitude question, I knew all of the answers by heart, yet me and Aurora came out fourth simply because I hit the "send message" button a few seconds too late. That's far from being a fair system. I stand by my suggestion of having the challenges posted at random dates and unannounced in advance. It will make the game a lot more interesting and noone should complain for not being able to read the boards.
