I was stationed at Lowry AFB in 1972-73.  One morning in Jan 1973 I work up and looked out at the large parking lot next to my housing unit.  The parking lot was larger than a football field and looked totally empty of cars.  After a few seconds I realized that overnight we had gotten a snow which totally covered every car in the lot.  Could not see any indication a car was even in the lot.  
Cold?  You get use to the cold.  But water still freezes at 32 deg and when the wind blows it can feel more than just a bit chilly by CO standards.  If it was FL it would be miserable cold.
