Those areas are crisscrossed by paved 2 lanes. A lot of it was doing 70 mph from town to town. But went up dirt tracks between mountains all the time. You have to realize even in rural areas of the Appalachians you have higher populations than out in the Rockies and Southwest. I might drive an hour on pavement, then down a washboard that takes me back a couple miles, sometimes more, then back to pavement and in to a town where I'd quickly knock off 20 stops in a condensed area. Had a remote ranch in Colorado that I drove about an hour and 15 minutes to get to at the end of my day then it was almost two hours back to my home. Had a ranch in the NM bootheel that was 30 miles from gate to ranch office and then another 25 miles to the owner's home if they wanted it delivered there. That station when they had two people running my area used to take a pkg about once a month to the customs house at Antelope Wells. That's 140 miles roundtrip for that one pkg. When I took over the mgr got Customs to agree to take it to their Columbus, NM facility. This is the area where mgrs decided to repackage and mail deliveries to keep me from getting overtime. They screwed up a good thing. Would've stayed otherwise.
