Hi, Frank Indiviglio here. I’m a herpetologist, zoologist, and book author, recently retired from a career spent at several zoos, aquariums, and museums, including over 20 years with the Bronx Zoo. This article covers some field observations of I and others, record-sized Black Ratsnakes, giant meals, captive care: http://blogs.thatpetplace.com/thatr...-elaphe-obsoleta-alleghaniensis/#.U_Ojw2NDV31
