I ski in Vermont and it gets pretty darn cold over here in the Saratoga area too. Don't use a metal drip tip. Like a cellphone keep the battery in an inside jacket pocket. Batt life will be shortened in the cold so if you are going to be out playing in the snow bring extra batts and keep them in a zip lock bag to keep them dry. Don't worry about
juice, it will thicken but won't freeze even at -30! PRAY FOR SNOW PLEASE
