Okay, so holidays have slowed down enough I can actually turn back to this.

Regarding the central location thing: It's there. People are gathering in specific places. You don't have to spread yourself out. Right now we have two of us posting in the South Carolina region and two of us posting in the Ohio Valley region. As people join up they can totally gather around either those locations, or others. 

I tried to centralize it as far as I could without being too limiting. If any of you don't want to post alone, you can always scrap characters and pick up new ones closer to the action, or you can get together with each other and collude to create new centers of action. The world is what you make it.
