Also ensure that you have chains or cables for the vehicle (depending on vehicle type) or 4wd. I even have cables for the rear wheels of my 4wd Sport Trac!
Extra food, water, TP, plastic bags for trash, etc. With the snow late today, and quite possibly overnight, check the road conditions before you leave, and LEAVE EARLY to come up here. Sometimes after a snowfall, the snowplayers/skiers/boarders come up at first light, and traffic can be heavy as early as 8AM.
But do come up, have a great time, and let us know how you did!
