ROUTES 40 and 66

Thought that I'd post link for famous routes from the 1950's. Route 40 is 3,222 miles between San Francisco to Atlantic City. According to this site, the mid 1950's were known as the Golden Age of Automobiling.

Judging from the amount of links that I have encountered at Google, I'd say that Route 66 is probably the most famous of them at all. I picked two links that I liked.
