I also read Roy's book multiple times, and I was not even there to "remember". After so many years of digging around, I sometimes feel like I was there.
I am always happy to share what I can on how to find information. There is a ton of good stuff out there, but so much missing information as well. Glad I could help.
I threatened Cal LLoyd once that I was going to come and steal all his stuff he has stored in his garage. He warned me that I would need a VERY large truck :-) Might be worth it!
