I think by the name, it should be somewhere closer to texas though it's hard to tell if texas is on the map, but nevada(New Reno) and parts of Oregon(Klamath/Klamath falls) are, and a desolate area of Idaho(Vault city and gecko are either bordering or in Idaho or Oregon), it would be too convenient to have it near NCR with the uranium mining, as NCR has become a central City of FOnline, there should be a considerable distance, to keep resources from piling up in NCR because anyone can make it back in one piece. This should be a town on it's own, and should spread players into other towns, there should not be a single central town, the population of FOnline is all centered in NCR, and just about every other town is empty or near empty. The population of the wastes should be a little more spread out, rather than focused into one area. What makes NCR so special anyways? There are no Resources other than cows and tree's in the general area(and you can find more tree's along with fiber and fruit at Vault city, as well as some close by mining spots. People are even suggesting that people start in NCR, when I believe new players should start in vault city because the only thing vault city doesn't really have in or nearby is a still, and it only has one brahmin pin.(At least to my knowledge) The hub has a great bit of traders, a still, a great mining area around it if I remember correctly, you can buy an infinite number of books, there's a good amount of cow crap to shovel.
I'm not saying NCR should be empty, but it's fairly useless in comparison to other towns, people should just grab their brahmin hides and head out to a more useful area to base their operations in.
