I'm aware that there are some discussions about eastern oregon trip in summer, but I'm wondering if it's also good to travel in winter. How is the weather and road condition? We are planning for the trip with our 3 kids, aged 10, 9, and 5 during 4 days of Thanksgiving holidays. We'll drive from Portland and stay in hotels. Any places we shouldn't miss, especially for the kids? Hotels or restaurants? Thanks!
