No water needed to be drunk, and very little sweat: maybe I should ridden harder!

The ride home should be above freezing: woot!
LaLa,
Be careful with the thinking on water. Winter riding and winter activities are very drying. You can end up with dehydration problems that rival those of summer riding. Colorado's winters are much dryer then we think so take water and try to drink it along the way. A Camelbak with an insulated tube will freeze less than a normal water bottle.
