Martin Milner and George Maharis

On October 7, 1960, the first episode of the one-hour television
drama "Route 66" aired on CBS. The program had a simple
premise: It followed two young men, Buz Murdock (George
Maharis) and Tod Stiles (Martin Milner), as they drove across
the country in an inherited Corvette (Chevrolet was one of the
show’s sponsors), doing odd jobs and looking for adventure 
while on a journey in search of themselves.
