Who doesn't enjoy an outing? This may end up being a trip down memory lane, and hopefully not the trip from hell. You won't find the answer in a Rick Steeves guidebook, that's for sure.
I'd say this was a solid Persian.

My testers on this were a fine group; Al Sisti, heidi and rjy, all of who probably felt they needed a day trip after to relax.
Nudges will be Friday of course and I am always available by PM before that.
Nudge Friday:
Nudge 1] Did 6D give you the feeling I was getting at something? Because I was.
Nudge 2] ...a word is too long" what does that usually mean in the meta world?
Nudge 3] Knowing that most constructors try to have their theme answers in a symmetric pattern does that help you any?
Nudge 4] 36A is more than a cultural hero from my ill-spent days as a college student in the 60's. He is not just an icon, he's an Easter Egg.
Full Blown Shove] Many people say their "intro" to the path home was the Vail clue.
One last BIG nudge:
With 6D in mind "Gauge (like whether a word is too long)" look at, for example, 1A and 30A. Does the wording of those clues (and 6 others) give you any ideas of how you might employ 6D with the answer?
The Reveal:
There were 8 clues with words that, like hinted at in 6D, were too long. Each clue was worded in a way to bring the shorter word to mind. For example 1A: Award for the best dish in a Food Network Challenge - MEDAL, but take away the D and you get MEAL. Similar things could be done for 16, 21, 30, 41, 50, 59 and 65A. Along with 1A if you took the "dropped" letters from them you got D R O P A C I D. Perhaps that is why the counterculture icon Dr. Timothy Leary, famous for his Tune In, Turn On, Drop Out book and his famous infatuation with LSD was smack dab in the middle.
