i have no idea if this is the correct forum, or if i should go for midwest or northwest, but . . . i am planning on moving soon - driving from chicago to portland, or in the first couple weeks of november. i have done i-80 across the country too many times and it seems like 90 and 94 take pretty much the same time. any thoughts on which is better? south dakota vs. north dakota? i would also appreciate any recommendations for places to stop by along the entire route (montana, idaho, washington). i am thinking about detouring from bozeman just to check out big sky. i know it won't be open, but i really want to see it and hope to get back there this winter or the next. thanks for any thoughts.
