These are based on entries in the Route 66 News blog. I just pick the ones of special interest to me. The site has many more articles on a daily basis along with photos and much more in depth coverage. Well worth checking it out.
Route 66 has spawned many new places. These are some of the ones that have opened in the post-"Cars" movie in 2006 and include built-from-scratch places like Pops in Arcadia, Oklahoma or revived places that had been closed or "moribund" like the Palms Grill in Atlanta, Illinois.
I will just do my two favorite states.
