This is a "take it along with you" travel book, but I enjoyed it just as much sitting at home reading it. The format is a delight with bright, colorful photos and easy-to-read sidebars. Some sidebars in other books make you lose the narrative, but these are set so as not to do that. The directions seem very clear, although I was traveling from my home, not in a car, so they are not tested. There is just enough information to make me want to hit the road and discover new sites and revisit old ones. There has to be so much on this route to be discussed, that the author seems to have done a great deal to make it clearer for the "double six" enthusiast or initiate to not get bogged down by the thought and just be ready to set off on a wonderful adventure.
