BTW, I wanted to add this cold is also affecting all the deer around here. I'm located on an off-grid survivalist's dream property here in Minnesota. It's covered with many dozens of apple and other fruit trees and hundreds of fruit shrubs, not to mention the hundreds of hardwood trees. The deer have made a huge mess of my backyard digging for apples under the snow. And they are all very young deer too. All the adults disappeared during the recent hunting season which must have ended now because the young deer are coming out of hiding now. But what a mess. Deer tracks all over the place. They don't even act all scared when they notice me noticing them any more. And I just moved here 4 months ago. Fortunately, all these cold days have been sunny, and that has helped a lot.
