We are moving from Houston to Seattle and will be driving in 3 weeks time. We are discussing which route to take. We figure on driving 600-700 miles per day; there are two of us. We need the trip to take no longer than 4 days (3 nights). We would love scenery along the way but do not want to risk getting stuck in a snow drift and want to arrive in our alloted time period. Questions:
1. Is it too dangerous to drive through the Rockies except on a major interstate?
2. Anyone please advise on which route is preferable overall?
