It's not been my typical MO, but I'm on day 3 of a 4 day trek from Tennessee to Colorado. I've seen a little interstate, but very little. It's been some US highways, a lot of state roads, and a few county roads (gravel and such) thrown in for grins and giggles. Day 4 will likely be all paved, but I've had fun on the gravel with my overloaded bike.
The first pic, in MO, I could see about 100 yards. The second pic, in KS, I could see almost 3 miles. It was a pretty cool view.
