Easy glitch see it off and on. Involves a cart and 2 people. That's my hint. IDK if I should just post how to lol Ability to walk through any building, mountain, rock, hill, person, cart, and water. You may also go up to a high point via your horse and walk 1,000 feet up in the air all around the RDR world. Good fun but I see people abuse it and that sucks.
