Only one thing that would have made the countryside much for interesting: Wildlife. How crazy would it that be to drive in the country and a deer comes out crossing the road? Use the rifle to hunt other animals. That would have been awesome.
I used this a lot to cut the distance between Angel Pine and Ganton. (Weapons, the most needed ones; spawn at Johnson House). This route is pretty much isolated. You can't hear or see the traffic or any humans, no glitter of city. And one abandoned Pick-up near wooden bridge to add some extra.
