If you have time for the pics at the beginning and the end of Rte. 66, do it. I have pics somewhere of the end of US Rte. 1 (Key West) and Rte. 66 (Santa Monica).
Just my opinion
i won't be going to the end. just don't have the time... i can hit the begining but not sure i want to go into chicago because of time and the muesum i want to see in st. louis... still have to map that a littler better to see what makes sense.
