Hello Travelers! I am flying to Seattle to collect my father's personal effects. I am renting a car and will be driving back to Little Rock, Arkansas. I have noticed that most sites suggest 2 different routes (both approximately the same length of time, save an hour or so). The I-90 route through eastern Washington, Idaho, Wyoming, Montana and then down through South Dakota, etc. The other route goes south through Oregon, Idaho, Utah, Colorado, etc. Which route should I take? Which route will be more scenic; therefore more enjoyable? I appreciate any and all feedback! Thanks!
