You should pass some signs of fighting, which will confirm that there are ghouls inside the Repconn Rocket Site. Follow the road and check the bodies along the way.
You can get this lead from No-Bark (who thinks that they’re communist ghosts) or by talking to Manny, who will be in the dinosaur’s mouth during the day. They want you to help move them out of there. The scavengers in Novac can’t salvage anything from the Repconn facility because a bunch of ghouls have taken up residence inside. You’ll probably get the lead for this from the citizens of Novac.
