I'm turning 60 this year so to celebrate the wife and I are going out to the west coast. We will be leaving from Minnesota. Maybe go through Colorado, never been there before. She wants to visit where here grandparents used to live and visit some long lost cousins. We only have two weeks so we don't have time to stop on the way. What is a good way to cross the mountains to end up in the south end of Oregon? We will be pulling a fifth wheel with a 3/4 ton 6.0 Chevy. Any must see spots? I want to take a couple of old train day trips.We are just in the planning stage. Late August to Labor Day. Dale
