I have a confession to make, but you will have to read this blog post before you’ll know what that is.
I woke up this morning to a very cold temperature. Nowhere near the coldest I’ve ever experienced, which was right around -50°F. (I remember that stretch of weather back in 1996, Minnesota set its all-time low temp about an hour away from where I live, that temp was -60°F.) This got me thinking about the climate zone I live in and heating degree days.
