We have yet to get frost on our windows, this winter. Also, my best windows for photos may not produce any; the frame was rebuilt during our home repairs project and new windows put in. For the time being we seem to have no storm windows, and so the screens are still in place. I am hoping that the screens are small enough mesh that we won’t get a build-up between the screen and glass. The temperature seems to be rising. May be a warmish winter, here.
Anyway, here is a frost photo from this date in 2014.
