Well for me it was probably the only time young JWs could find any common ground with fellow students on the anti-war issue, I remember how anti-establishment everybody was. One guy in my class thought it was "cool" that I got to stand out in the hall during the national anthem; I guess he saw it as some sort of rebellion against the "system" Lol
Concerning the Cold War, JWs never felt a nuclear holocaust would ever happen because Jehovah would intervene with Armageddon. The main issues the Soviets created for JWs had to deal with trying to function as a denomination under the Communist regime, as did some other small religious groups as well.
Then of course, by this time the excitement regarding 1975 was really starting to gain momentum. JW youth were barraged with encouragement to forget about any plans for a career and pursue "Kingdom interests" by "pioneering" after high school, or to "reach out" for more congregational responsibilities.
Non JW related memories HAVE TO INCLUDE the awesome muscle cars of the late '60s, as well as the music.
