Oak Grove was my favorite course of the 5 we played over the weekend. It was supposedly the first permenant basket course which is cool. Like Evergreen, it is a course that requires many different kind of shots. The interesting thing about Oak Grove was the random baskets and tees throughout the course. There were at least 3 entire holes that were not on the course map but fit in perfectly with the way the course winds around and through the park. So what is listed as a 19 hole course actually winds up being at least 22. It made me feel better though that even the locals who play that course all the time don't know exactly how to navigate it.
Absolutely worth the drive, and I hope to play this course a lot more in the future.
