haha yeah, Michigan always feels like it needs to test you in the winter. I'm not worried about keeping my herp room warm in the winter (it also houses a tortoise and a boa who both have heat sources.) Lately, it's been hovering around 80 and I'd really like to drop that a few degrees before I get my frogs. And like I said, I don't really want to open a window but it also feels silly running an AC when it's 55 degrees outside.
