Frosty Morning

The thermometer at my house this morning read -30F.  The radio said that it was -38F in some places near here. That's the coldest we've seen in several years. I drove Diane to work and coming back across the Racquette River in Potsdam I saw this frost and mist as I crossed the bridge from Fall Island. Whoever left those tracks trusts ice farther than I would but they do add an interesting element to the photo.
