LOL Well I'm not necessarily a brave soul... after all it's a nice comfy 72 degrees in my office . I let it get down to about 63-65ish at night but I have a nice warm comforter and three snuggly dogs . Having the right "gear" is the secret to survival though that's for sure! The plow trucks here are gigantic too compared to the little ones where I grew up. But they haven't had to plow much this year!
