How much do you value your car and the lives within it? How about the lives of others on the road? Look, if you're on all seasons and haven't had time to warm up to driving in winter conditions recently, I wouldn't tempt fate. Lots of people are in here saying "there's no snow right now," but this is New England, our winter could very well become more severe in the time between now and then. As for "as long as there's no hills," this is Vermont, even Burlington has hills that will make an unprepared civic embarrass itself w/out traction. Truth is, the cheapest set of road rumbling winters will be better than the most expensive all seasons, I'd buy some or rent a vehicle with winters preinstalled.
