The EZ66 GUIDE was developed by Route 66 historian Jerry McClanahan and The National Historic Route 66 Federation to make it as easy as possible for travellers to find and follow the various alignments of Route 66. The guides have been used by thousands of travellers from around the world. The 200 page guide is spiral bound, to make it easy to use while travelling. It includes easy to use maps you can follow going EAST or WEST.
I personally used this guide and found it invaluable. In my opinion everyone should have a copy of this if they’re thinking of driving Route 66. It's a complete "must purchase". Brilliant.
