We are having sub zero temperatures this week. Yesterday's high in Denver was -3. Not a typo, 3 below 0. Low for the night was -32. BUT on Friday we are going to be reaching the low 40's. yeah! OK, it is winter, we get it Spring is coming.This morning at Gobbler's Knob in Punxsutawney, Pa, Phil the Groundhog, was raised from his burrow at sunrise. It was reported that he looked around and did not see any shadows, therefore, we will have an early spring.
