I'm torn between the 80s and 90s. They're my two favorite decades and I'm sad that I'm really only able to experience them through YouTube videos and music. I was born in 93, so I don't remember much at all from the 90s.
I want to say the 60s, but I know that things were obviously different socially, and I wouldn't want to go back to a time where racism was much more rampant and blatant.
