Trivia

 * An NPC named Ray Warthington can be seen gambling in Armadillo and Thieves' Landing, namely playing Five Finger Fillet or Liar's Dice. It is possible this is the owner of the ranch, or a family member.
 * A woman named Louisa Warthington is buried at Odd Fellow's Rest
 * The barn is very similar to the barn found at the Marston Ranch in Beecher's Hope.
 * It seems that harassing or pointing a weapon at the woman makes her hostile, and she may pull out a Double-barreled Shotgun, seemingly out of thin air.
 * Sometimes, if the player kills livestock the women will shout: "Who do you think you are, Holstein Hal or Ike Bollard?" As a reference to a Red Dead Revolver character and one of the leaders of the Bollard Twins Gang.
 * It is common to see coyotes catching and killing chickens wandering around the ranch. The man will also shoot at the coyotes when he sees them stealing his livestock.
 * It is a good location to hunt animals such as rabbits, skunks, and raccoons.

Bugs

 * A glitch allows for a deer and 2-3 coyotes to spawn in the pen with the rest of the animals.
 * Possible location solution for the 31/32 Nuevo Paraiso glitch.
 * Snakes have a tendency to spawn around the ranch, putting the Warthingtons in danger if they go near them.
