In my mind, 1967 was the year of the big change culturally. The so called hippie “Summer of Love” was a big marker in what went before and what came after. 1967 was the true beginning of what everyone now just calls the ‘60s. I was 17 at the time and remember it vividly. Up until 1964 or ‘65, it was still the ‘50s culture in America.
Opposing viewpoints:
I was also 17 in 1967 and I agree with your comment except offhand I thought it was 1968. Regardless, the hippies set out to change the world, and they have, but not for the better. I wouldn’t want blacks to be treated as they were in the 1960s, but other than that, I can’t think of a single positive change.
