Although the series was called "Route 66" many of the episodes were set in areas in the United States which Route 66 did not travel through. For example, Route 66 begins in Chicago and ends in L.A., but two episodes were shot in New England, one in Maine (Year 4, episode 2, Same Picture, Different Frame) and one in Vermont (year 4, episode 3, Come Out, Come Out, Wherever you are) - both aired in the fall of 1963 and starred Martin Milner and Glenn Corbett.
