Next time you're by Storms Driving Range, walk around to the back and take a right to see the most well-built tree-house I've yet to explore. A second, smaller one lies nearby, but the first treehouse is where it's at. Warning: you'll have to cross a river to get into the field, which lies beyond Storms, unless you cross the grassy ridge in line with the middle of the driving range.
