What figures, either in circumstances where they lived or circumstances where they were in slightly different positions than the OTL, could have been Hippies or at least partaking in counterculture trends?
For example, there is at least the rumor that LBJ -after leaving office- turned into something of a Hippie, and certainly he grew very long hair and wore relaxed clothing in his post-presidential years. If LBJ never got to the White House, could this trend have started earlier with Lyndie going full on counterculture? If JFK lived, could he have gone the Bobby route and grown out his hair and grown sideburns? If Buddy Holly or the rest who died on the plane had lived, could they have grown sideburns, Dylan-fros, and beards, and started playing topical folk?
