I also noticed the slight change between Ojos and RM 80. Specifically between RM60 and 75.
Are you guys sure about the changes after borrego? To me it looks like the course goes out into the wash for a bit then heads up to the highway and stays right along the highway the whole way up to the road crossing. Same as 2009. So if you are on the highway the race vehicles will still be right next to you.
