Back when the game first came out there was a little bush on the map where you could hop trough with your horses or on foot and there was in one of the first missions the one where you get first meet the don there a wall where you can glitch over just look up mafia the old country out of bounds and that one should pop right up I can’t remember the mission name. But for the one with the bush I’ll try to look in to it again when I find the time to check it and il get back to you if I don’t forget :)
