OOOOhhhh, -4F makes my shoulders & neck ache with just the thoughts. We are 37F and rain. At your temps, I would be staring at the roaring fire thru a glass of magnificent amber fluid. Thoughts of the out-of-doors, furthest thing from my mind.
Oh, I hear ya! Gets a little harder every winter to put up with the cold. -4 used to be Tee-shirt weather.
