I will be making this drive and I have a couple different options. The first option is I-80W and I-84 W which would take me across Nebraska, Wyoming, and Oregon. The other option is north from Memphis to Sioux Falls and than take I-90 W across Montana and eastern Washington. The latter sounds much more entertaining to me and incorporates the possibility of going to some vineyards in WA. What I'm wondering is if anyone has any experience with these two routes and what are thoughts? Thanks!
