Native Trainer/North Yankton is a mod created with GTA 5 Scripthook that allows you to move to the snowy North Yankton. To install, simply copy NativeTrainer.asi to your GTA V root folder, replacing the existing file. In the game, press the F4 key to open the trainer menu and find the North Yankton menu item, then click on it to load the map. The North Yankton map will appear in the southeast part of Los Santos. You can teleport to North Yankton via Trainer's Teleport, but make sure you load North Yankton first before teleporting.
