My home is in Peyton, Colorado. It is just east of Colorado Springs. People hear Colorado and think "OMG, that is blizzard country." It isn't true though. We only get regular snow in the mountains. Denver and the Springs see a few storms a year but usually the day after is clear and the snow is melted.
An engine block heater might come in handy on the coldest days or if you are moving to a ski town. It is a wasted anywhere else, especially if you will be parking in a garage.
