My family will be moving in 3 vehicles this March. We are shipping all our belongings in a POD so we can just drive our cars-- a caravan, toyota and honda. No 4-wheel drive. Is rt. 80 OK in mid-March? Just a little apprehensive with snow/ice/rocky mountains/etc.. Any advice? We figure about 8-10 days from Boston to Portland. I've now read MANY, MANY threads but I'm still confused about the conditions of the route in mid- March. I know there may be snow but is it more severe than in Jan/Feb? Is March a more manageable driving time?
