I'd like some advice as to the best routes over the mountains. I'm planning a move from Portland OR to St Louis MO. I will be traveling in apx two weeks. Traveling very light in my chrysler Concord. Time is not a factor but safety is. I've heard that there can be some nasty snow storms and ice crossing the rockies. Will I miss the worst of the winter weather? What routes have others taken to cross the country? I'd appreciate any advice or recommendations. Thank you.
