There is a multi years old thread on this forum that Google brought up on B. subocularis care, mentioning a guy named Dusty Roads (Rhoads?) as an expert on subocs and rosalie snakes, and an article (radio interview?) on Herp Nation Radio about them. I couldn't find the reference on HNR's site, but DID find a book on the Trans Pecos by the same author on Amazon.
Ordered. Can't wait for it to arrive.
I love books.
