You see, I can understand that, but I went with the completely opposite solution. I use mods to make sure that there is at least a good chance that there will never be nothing ANYWHERE for long, no matter how many times I go there. Like http://www.nexusmods.com/newvegas/mods/50423/?tab=1&navtag=http%3A%2F%2Fwww.nexusmods.com%2Fnewvegas%2Fajax%2Fmoddescription%2F%3Fid%3D50423%26preview%3D&pUp=1 for example. One of the problems I have with New Vegas is that the spawns are too static and predictable. It needs more chaos and randomness. And Endless Warfare brings chaos in spades. With it you can turn the entire map into one big war zone if you want to, though I don't go quite to that extreme. But you get the idea.
