I would love to hear more about your experience there (my email is miles at coderpath dot com), and would like to learn more about R.G. My only knowledge about him was through his autobiography.
Not sure how much of it overlaps, but I've been going through the biography "God Runs My Business" which is from the 40s and might show more detail from that time in his life. It's definitely a product of that era, too, just in the way different subjects are brought up, so I think it's interesting for that glimpse into the USA as well. There are lots of pictures as well. A very interesting man.
I'll have to read that as well. Thanks for the tip :)
