Winter gets old (especially as I get older). Not so much for the cold, but for the gray skies and lack of sunshine. We get 100" of snow a year, but seldom get below 0 more than a handful of times per winter. -15F in almost unheard in this area and only happens in the dead of a crystal clear night.
I still walk the dog, maybe not as far and with a bit more vigor. I let the car warm up a bit longer. I don't mind plowing the driveway or shoveling our walkway. I might alter my plans somewhat, but will do anything that's pressing.
So, as of this point in my life....the cold? Bring it!
