If you’ve got time to kill, you can watch this 76-minute video by Chris Gillham using time-lapse photography of a Route 66 trip from St. Louis to Santa Monica, then St. Louis to Chicago, in a 1965 Pontiac Parisienne convertible.
The camera he mounted shot an image every 10 seconds. The Route 66 trip was in June and July of 2011.
He had to jump on the interstate somewhat to make up for lost time, but he also made plenty of stops on the Mother Road as well. More of his photos can be seen here.
He skipped Afton. Bah, humbug. Nice video, nevertheless.
