Nice topic! In NVBII there is a bounty on "Bloody Brad", where upon approaching his location you will hear about the "Legion gold". This whole storyline is reminiscent/a reference whatever, of the movie "The good, the bad and the ugly". It's even more obvious since Bloody Brad is having a three-way shootout with "Tuco" (The Ugly, played by Eli Wallach) and "Clint" (The Good, played by Clint Eastwood). In Russell after Galton slaughtered the Sand Wolves. Check their camp and the cave on the hills (west from the camp I think). In the cave, their is 4 volumes of journals beloning to a Benjamin Hines. He's a Follower of the apocalypse sent to study the sand wolves, which story share many similiraties with Caesar and Graham's. (They are even mentioned in the journal) It's a long and interesting read.
