What a pleasure it is to hear from Rang's sister. I would like to communicate with you if you have an email address or another method you prefer. I knew Rang when he and I were on a survey crew working for Ashley National Forest in 1970. He and I became good friends. I may have some stories about that summer that you would like to know. I have remembered Rang for almost 40 years now.
I am uncertain that a public forum is all that appropriate though.
Please contact me at firstname.lastname@example.org or let me know how you would like me to contact you.
