[@Hallion] Are you talking about the feral population of the Nosferytes? If so, Tyler said the non-feral Nosferytes are unaware of the growing population of ferals in the mountains. Other than that, I don't believe they have an actual society as they go completely animalistic once they become feral. 
As far as them traveling, I went off the assumption as long as they protect their fair skin from the sun they would be fine. Tyler had no objections to me going off that assumption.
