Frank,
Yes there are authors out there. I had an article published in Reptile& Amphibian Magazine on the captive husbandry and reproduction of Eastern Indigos (Drymarchon corais couperi) and Dean Allessandri had an article published in Reptiles Magazine on Eastern indigo snakes(D.c.couperi) which went into detail on natural habitat and radio tracking techniques. There have ben scant few GOOD articles written on Cribos, esp blacktails. I beleive that Juergen was going to come out with a book on ALL Draymarchon, but havent heard anything about it in a while. Doesnt mean it still isnt comeing. your best source of info on cribos are the folks on this forum. they are a wealth of information indeed. Email them and probe their brains for details. I'm sure they will help.
Take care,
