Anyone use this book on CDT? I understand they have put a lot of work into this and into the trail. One is able to download all the gps points they have in the book (fully gps'ed). Looks like J. Ley has some competition. I like to see this-an official trail, official maps and books. It is confusing at times all the different maps and etc., on the CDT. I wonder if AT or PCT started out like that.
