Are you telling me you have no way to monitor the temps of your balls? Really? And while I may not have kept snakes for decades upon decades, I have kept them for over ten years, and I've never heard of anyone advising not to monitor temps. And to date the only major problems I've ever had in my reptiles are from the ones I've adopted that were sick, and I adopted them solely to save them from neglectful owners. I take a great deal of pride in providing the best care for my animals that I can, and I refused to be shamed for that. I've seen big collections, small ones, professional ones, and everything in between, and not one of them has simply taken for granted their temps because the temperature outside was in the 90's. Some people do use climate controlled facilities because their collection is far too large to have a heat source or thermostat for every single tub or enclosure, but I don't know any that ignore their temps completely. I don't know one that would advise to ignore temps completely simply because of a geographical location.
