This year there will be a roadbook only section of the course. That means there will be NO GPS tracks for that one section, no paper maps, nada except the roadbook. So, EVERYONE will have to use the roadbook in that section, or follow someone who is. It's a new section off the standard routes, so nobody will have a clue where the course goes without the roadbook.
The remainder of the course (95%) will have GPS tracks. BUT it looks like both the roadbooks and the GPS tracks will not be provided for any stage until the evening before that stage is raced. So, when you finish one stage, you get the GPS tracks and roadbook for the next stage, no sooner. The traditional AAA "paper" map provided ahead of time will not have the course marked on it this year, only the points where it meets the highway will be on that map (so crew know where to go for pitting).
Direct your critique and questions to Ken Cameron. Even Mike Pearlman doesn't know exactly where the secret section of the course goes. Oh, and there are other major and minor course changes too. It isn't the 2012 course anymore!
