It has turned cold in Central Oklahoma. Temperature about 30 degrees. We've had snow, ice, and mixture of freezing rain and rain. There is a layer of ice on the trees and high lines, our roads are icey. I'm hoping we don't lose power. I don't know how far south this winter mix will go but this is our first winter cold snap. I'm getting my backup oxygen tank ready in case we do lose power. It is something of a hassle if I'm not prepared. I'm setting in my office and it's a bit cool. Made a pot of coffee and pored it in the thermus. I'm going to have a ham & cheese sandwich, a cup of coffee, and read for a while.
