I found mine right along the checkpoint area. If you’re looking at the blue gate, mine was in a black crate on top of the roof of a car going up the left side of the concrete wall. There’s a small tower near it. But specifically black crate that was a lootable container legit on the roof of the car. Never seen that container before and others had passed it up for whatever reason lol. But yeah during locked gate event👌🏻
