Oh gosh, where to start. Well, I grew up in Alaska where pot was legal until about the mid 80s when they made it a misdemeanor (it was legal to possess for your own use one ounce, but it was not legal to sell or buy it).
Matanuska Thunderf**k which I have heard now possesses one of the highest THC concentrations of any crop worldwide was known at that time as “ragweed” because it was so crappy.
I actually drove a Vista Cruiser, but mine was yellow and named the “Banana Boat”. Later on my dad let me use a cop car he’d bought at an auction. My cousin and I actually had matching used cop cars.
In Anchorage things are so spread out you had to have a car to get anywhere, so most of us teens owned or had access to one.
I remember it as being a time of innocence and fun. I watch that 70s show and recognize a lot of the attitudes my friends and I had “back then”.
Some of the stuff they show wasn’t really around yet, at least in our area, but the characters and the personalities they got right on. At least insofar as the people I went to school with and grew up with.
We used to spend a lot of time on weekends “cruising the strip” showing off our cars and meeting other teens. Which I understand is illegal in many cities now. How sad.
School functions and being “part of the crowd” was really important. I knew lots of “Jackies”. Going steady was the thing, being a “slut” was bad.
Keggers were on, we had Senior Skip day every year, and we would sneak off (yes, even those of us who weren’t yet seniors) to various parks for a party on those days.
Disco was fun, but as someone else said, it was “cool” to pretend Disco sucked. And hey, some of it did.
The 70s didn’t really have any meaningful “anthem” or theme to it. The 20s you had the “roaring 20s” bathtub gin, prohibition all that stuff. The 30s was the “Great Depression” The 40s was the war and rebuilding after the depression.
The 50s was the canonization of “the American Family” and also the “birth of Rock and Roll”.
The 60s? Hell, Free love, hippies, protests the whole “evolution” thing.
What did we get? Those of us that came of age in the 70s?
The Bee Gees and Disco Duck. 
I wouldn’t trade it for the world, it was a fun time to be a teen. It was a lot safer and freer than what the world looks like in this day and age.
(geesh! any minute now I’m going to say “whipper snapper” or something).
Maybe post some specific questions and we “old folks” can help you out.
