The flat lands in Colorado leading up to the Rockies are nearly as bad a Nebraska. I-76 is brutal.Did some work for a facility in Western Nebraska. Had to fly into Denver and drive like 4 hours to get there and I'm pretty sure I didn't see a car or hint of civilization for like 30-40 minute stretches at a time. And it's not like it was hilly or anything - it was flat and desolate as could be.
