Where do you mean by Lower? The southern Appalachians? Or just somewhere in the foothills, which could be anywhere?
The southern Appalachians are still a long way from the sea and there's a lot of dams along the way so I don't think we'll be going there any time soon. Though this early on after the War we should be able to find intact transportation like a car or motorboat or even jack a train or something.

I'll be honest, I'm struggling with the stats. It might be easier to do this in a video game UI but I can't keep track of the numbers and calculations.
