I look at the photos ... before the Iran Revolution, the Soviet invasion of Afghanistan, my sense is relations between India and Pakistan were less tense, a time when Turkey was much more secular than today. The photos make me wonder "what happened to the youth in the pictures? To the families who hosted Rick and Gene in Bulgaria, India and elsewhere?"
1978 was 47 years ago. If we use "half way timing" it was the half way point from 1931 to present. Think of all that happened during that time of 1931 to 78, then 1978 to now.
I graduated from college several years too late to be able to go on the hippie trail but appreciate the photos and look forward to the book. I did get to see some of Istanbul and Bulgaria 9 years later and the photos look similar to what I saw. Most memorable are the personal interactions, the curiosity of people to meet people from a very different background.
