We're planning a trip up the Pacific Coast to Seattle in March, then turning right. We'll be driving from either Spokane or Sandpoint in Idaho to Missoula, and by then it'll probaby be the first week of April. We wondered if we could drive the route on Highway 2 via Kalispell, which will be much more interesting, or if we should plan to play safe and take I-90.
I've never been to that part of the States and it's a long time since my wife was there. Any advice on what we might expect at that time of year?
