Honney, You are not EXACTLY correct about wind chill not affecting inantimate objects. I will try to explain short and to the point. The harder the wind is blowing the more heat (or cold) is being drawn away from the object that the wind is blowing against. Take an overpass for example. If a snowy road is salted and the water is sitting on the bridge, the water will freeze faster if the wind is blowing than it would if the wind was calm.
Objects left in the cold will not freeze any faster as long as the wind is not blowing against it. Folks insulate their household well pumps with a wooden box and batts of insulation not to actually keep it any warmer but only to protect the pipes from the wind.
