Bought this guide for my trip along the mother road, the book is great and maybe too comprehensive to be used on the road without having about 3 years for the journey, we had 10 days to do 2500 miles and I wanted to see everything, we managed to get a map in Oatman, Arizona, which mapped the whole of route 66 and all the sites on A1, that took over and meant we could map read at pace and not miss anything, so what im saying is this book is fantastic and shows literally everything at close detail so every remaining route 66 mile can be covered, but anyone with not much time for their trip should probably steer clear.
