Any ideas on the best route - I know the quickest is 80 and then up through Idaho and into MT...have done that in the summer.
Now that we are planning a winter route a bit concerned with all the mountain passes increasing the duration the trip.
Would it be better to head up to Portland on I-5 and then connect with 90 over to MT?
Which routes have the least amount of mountain passes that tend to be the best plowed?
Thanks in advance!
