So I'll be visiting my brother in Seattle on April with my dad. We want to make a 5-6 days roadtrip outside of Seattle. Dad's already been to California and some of the parks. We would really like to drive north to Vancouver and see some Canadian Rockies. Any suggestions on where to go and what weather should be expected in early spring? If it's too cold/all frozen up we might have to pass. Yellowstone is another option, but that means spending a lot of the time just getting there, plus it's probably still all frozen up in April. Any suggestions/hunting cabin invites?
