BB in ref to your upthread poem by KGibran. I love that, he He wrote with depth & I recall buying the first book he published back in the day. I felt like I had found my soul. Lol. I also bought a book caalled. "Johnny Got His Gun". That book did cause some controversy due to the Vietnam War issues at that time.
It was typical of the times and the message of a generation.
With no social media, the writings & music carried the message instead. I believe the college campus became the center for much activity & organizing.

May I ask the age of your hippie father?

I miss my old hippie friends from back then. Seems like the country evolved so rapidly but maybe that's just age remembering.
