We are travelling by car to Massachusetts for a week, going through Western New York. (I-90) We are from Canada. Our hotel is booked for Sat., July 5th. We plan to stay overnight on the way (prefer not to drive for long periods, nor in the evening). We were thinking of leaving the 3rd of July but we wondered what the traffic patterns would be like considering the July 4th holiday. Or would we be better to wait until the 4th (midday) ? Would traffic calm down a bit by then ? Or is it just as busy? Any suggestions?
