|Subject: RE: Re: Italy to Switzerland by Car?|
I'll leave it to others to answer your weather/driving query but you should be aware that Zermatt is a car-free town (with the exception of a few local electric vehicles). When we were there in '96, we went by train. It's described in our Switzerland travelogue at http://www.thetravelzine.com/swiss1.htm.
Enjoy your trip, Don&Linda Toronto
