the winter witch blew through

Ok, so I was driving through this new development outside of town, "in the mountains" and there was a patch of forest - just a patch - that had frozen over.   It looked like the witch from the Chronicles of Narnia had come and froze a little plot and then departed.  Really, there was a sprinkler installed that was malfunctioning and that's all there was to the new development.  Maybe they can wait to install sprinklers next time until the house is built?
