I wonder where they would be set up though, I'd imagine it'd be near a place like RetCon with high value pre-war tech.
I'm more interested in what they are currently doing,
Are they still finding technology?
Are they guarding technology?
Have they given up hope?
Are they planning an alliance or something?
Waiting for back-up?
If there's only a few left what is forcing them to hold their ground in New Vegas?
