Two heat guns and six digital probes. I keep chameleons so I'm a paranoid nerd on those temp requirements.
I've got Bob Clark friended already, and I was checking royal constrictor designs as I posted this thread, so it seems great minds think alike! Do you know of any forum members/good breeders active in the Portland, OR area? When I was just starting out with chams and geckos I got lucky with a local mentor to help me through the process, and it'd be good to have someone local who can evaluate my stock/breeding plans.
