I am planning a road trip during Thanksgiving break from Nashville to Seattle. Could anyone give me any tips as to whether I should be taking I-90 via Billings, Missoula, Spokane or I-80/I-84 via Cheyenne and Boise? What troubles, if any, can I anticipate in either route? I will travel with my wife and elementary school aged son. I am trying to make this trip fun and make it like a mini vacation. Also can I get any suggestions as to what places to visit along the way, specially in order to see the spectacular landscape and vistas of the Northwest. I understand many National Parks will be closed due to Winter. I was not aware that the parks close for Winter until recently :(
Thanks a lot.
