Well, I was planning on starting off in Virginia, I heard there was a mountain range there that extends south into Georgia, doing a quick search up it's called the blue ridge mountains and as far as I can tell just looking at the topographical map of Virginia there are a few places where I can get fresh water, I'm not sure however how farming would look like, but just reading about the geography tells me it might not be possible in such a forested and mountainous area, this is of course not mentioning the possible effects of the super weapon strike nearby and how that would affect them and the area around them.

Demographic wise, I can see that there would probably be more Caucasians than there are African Americans that would survive, I'm not sure about Native-Americans or whether there are Native-Americans in Virginia. Religion would be heavily influenced by Christianism maybe even changed to a point where it can no longer be recognized as Christianism, and significant historical event that could be preserved would be the civil war thus having heavy connection with the Confederacy. This is as far as I got into making the Nation for the RP in terms of concept.
