I travel on it every day. My workplace, the National Hot Rod Association, is just off it in Glendora, CA. The cities in that area just went through a 'nostalgic period' and renamed it Route 66 (although not all of the signs have been changed which makes it a little confusing). It travels from Glendora, toward the sea, through Pasadena (where it becomes other street names) then out to the pier in Santa Monica. Millions of people probably travel on it each week and don't even know it. On my many drives into AZ I have wanted to take the small stretches of it where you see the signs "Historic Route 66, NEXT RIGHT", but then I worry for my suspension, as CA and AZ let it go out in the desert. But it would sure be fun to someday make it out to Chicago on as much as the old Route as I could get there on! Happy Roadtrips!
