Oh, I remember Vietnam. My brother was a Navy Seal. He was sent to Vietnam and served with the Marines on the Riverine Boats (aka Swift Boats); we worried about him constantly. I had classmates who joined the military and served in Vietnam. Some never made it back and others came home physically and mentally damaged from the experience. This was happening on a national level. I also remember the nightly newscast of the number of casualties; the reels showing the caskets arriving and the families grieving. All of which led to a whole generation questioning the government and protesting to end what we came to believe was an unnecessary war. This was the beginning of erosion of public confidence in the government.
We were willing to question everything; break the rules and establish new mores. We also lived through chaos, MLK assassinated, JFK assassinated; Woodstock; emerging push for women's rights; civil rights marches, etc., etc.
It was also the era of the Beachboys and Mustangs, Mary Quant, the Beatles, Joan Baez, Bob Dylan, psychedelic colors, available birth control...........so, so many things!
