I was able to walk today for the first time in a week. It is very cold but not as cold as these photos would suggest. I didn't slip on any ice like last week but I did trip on a piece of sidewalk that has heaved in the freeze thaw cycle. I wouldn't want to believe that I could walk four miles and not have an incident of clumsiness on some level. It was foggy overnight so all the trees and shrubs are covered with ice crystals like they have been sprinkles with sugar. It was lovely.
