I am thinking about driving to Los Angeles from Montreal Canada this December. I am prepared to take a week to make the trip. I would, if at all possible, like to minimize winter driving conditions. Is there a recommended southern route that could do the trick? I've tried Mapquest, but it looks like the weather for most of the trip will be wintry. I am prepared to add several hundred miles to the route if it means that I can avoid he snow. Thanks.
