So, near the fire ant mound, somewhere around the strip, is the Abandoned Warehouse you're instantly transported to when you do the quests for the Van Graffs in the Silver Rush. I'd already done that quest, so when I found the place several days later and went into the Abandoned Warehouse, instantly 4 or 5 NCRs go running for the back of the warehouse, and the 3 Legion guys that were originally knocked out are just standing there, they all sort of have generic voices and you can talk to them but they just say "what's up?" and the only option is "goodbye". Kind of funny, they're not hostile (even though I'm vilified by the Legion), the NCR completely ignores them, and they don't have anything on them if you try and pickpocket them. Also apparently shooting them doesn't result in any status changes, though killing the NCR members running straight into the back wall does. I'm guessing they never expected anyone to actually go into this place? It's not a marked building/location. Kind of funny.
