This morning the thermometer read -30+C (-20F). I can handle a couple of days without some hard physical exercise, but after that, cabin fever sets in.
It warmed after lunch to a balmy -18*C, bright and sunny, no wind, so me and the dogs went for a 10 km x-country ski on the lake.
Multiple light layers and wool gloves inside thinsulate mitts kept my hands warm.
Glorious to be out there! Makes you wonder how all the critters survive under these temps, especially the little birds that don't migrate. I make sure to keep the bird feeders well stocked.
