NC to Portland, OR
What is the best route to take to avoid the most mountains as possible? What is the quickest route? Any side trip suggestions? We have to be there in 6 days!
First, for a fewest mountains kind of route, I'd work my way up to I-64, take that to St Louis, then I-70 west to I-29, that north to just south of Omaha and cut the corner of NE over to I-80 at Lincoln (you could use SR2). Take I-80 west but cut the corner of Wyoming as well, avoiding Salt Lake City by taking the two-lane road through Kemmerer and pick up I-84 for the rest of the way to Portland. You cannot avoid hills, but those on this route aren't so bad. Bob
