I got feedback from friends and they wanted to know more about Hippie and counter culture. So, I am giving two links which will give more info on the same. Samsloan's site would be banned in some places. So, i'm putting other than the home page one can explore the site by following links below that page. And, thanks Rinks for your encouraging response.
