Found a train tunnel off Nipton. Dead guy in power armor. His group was trying to blow the debris and move off to god knows where. Says I need 5 satchels of C4. If I can find any. Maintenance tunnel with dead NCR rangers and a note about ordering all civilians in the Mojave to evacuate to various other places, otherwise they'll be shot. Heh. Wonder how these guys all died down here. Let's see where this smaller tunnel leads.
