The last best looting spot in the northern part of the Battle Royale map is Pleasant Park. This location has a lot of houses, but really, there is only one building in the area worth mentioning -- a modern three-story house that is located in the south-eastern part of the park.
The chest is hidden inside the garage, so use your pickaxe to bash the doors and loot that chest. But don't leave just yet! Check the house itself, especially the upper floors. There are no chests spawning inside the house, but you will find some random single items scattered here and there.
