I played a pick up hockey game at -20f -40 wind chill and our breath was ice crystals. So beautiful.
Don't be too macho about playing when the temp is very cold. If you've never read "The Cruelest Miles" about the Alaskan serum run that inspired the Iditarod Race, some of the dogs that were relieved mid-way had run so hard at such a low temp that the cold had frozen some of their lung tissue which, when it began to thaw, caused profuse bleeding which meant those dogs perished for their effort. Balto is famous, although he was not the most heroic dog on the run (that honor belongs to Togo), and certainly he did not give up his life in the effort. Extreme cold can be dangerous for your extremely thin, delicate respiratory epithelium.
