There's a set of bridges in the southwest region of the map right below that big farm. They're in a big canyon area. They're bugged, if you throw a tomahawk or knife at the ground, where the planks of the bridge begin, the bridge will spaz out. It can get so bad that you can send yourself flying out of the playable area and into the Mexico area. It's extremely fun, I suggest you try it out Best part of it all is that if you get a successful launch, you take no fall damage wherever you land
