I thinks adding in the golfing mini game would be fun. As a place to go mess around with friends and feel rich. Maybe add an interior to it and charge for access like a membership. Or even make it a business that could go for auction and be run by them. And have a rental for golf carts.
the paleto forest used to have a extra mod for more trees like the actual red woods there irl. I think they should be brought back as they made the place look a lot nicer instead of being a decilate location and area in general
