I'll declare my bona fides right off the top; I was never a hippie.
Nope, the free love era passed me by without so much as a backward glance.
But I did meet folks who did the mythical "hippie trail."
That's where your hippy-dippy types landed in Amsterdam and, due more than anything else to indulgent parental financing, found their way south and east in search of inner peace and cheap hashish.
They'd traverse Turkey and Syria and Iran and Pakistan and find themselves in India. Usually a couple of weeks of India would clear them right up and they'd head back to the safety of Europe.
The hippie trail.
Now the denizens of many of those lands along the hippie trail are making tracks to mother Europe.
