An interesting question:
For me it would depend on what year. The very early 80’s are like a blur to me. Forget anything before 1983.
If it came down to music and movies, I’d say stick me anywhere between 1984 and 1986 and leave me there. Between Duran Duran and John Hughes flicks, I would be in Heaven!
If it came down to growing up and moving on with my life, I’d say between 1988 and 1989. By then I was driving, working and graduating. We finally had cable. I was living large!
As enjoyable as those years may have been, unfortunately they weren’t without pain. I lost my grandparents in the 80’s, money was extremely tight with two parents on unemployment and school sucked. My younger sisters were born in the 80’s (not that it’s a bad thing).
So if I went back, would I stay? No, only because life moves on. But I’d make sure all those great tunes and films were packed in my Gucci bag to take back to the future.
