What you said there didn't exactly make sense...the 4th station you visit IS NCR. I started in Boneyard, spoke to the 4 people there, the 4th tells you to check the next station, you continue to San Fran and ask 4 people again, the last tells you to go to VC...the same happens in VC so you continue to NCR station, ask 3 people (who know nothing) and then supposedly onto the Shady Guy who is meant to tell you the location, but instead he says....as I already said..."Don't bother me"
