Since 1984 the route was not so important anymore and only a few small cities and shops along the route survived. On the website You can find a lot of picures in information. We traveled the route 66 from Flagstaff till Los Angeles through the Mojave Desert. With the famous Joshua Trees which look like large cactuses.
Real great. The best time to travel throug the desert is in spring or autumn otherwise it can be terrible hot and don't drive without gasoline and water. One more: keep your limit when You drive the Route, because even if You see nobody, Police is around the corner.
