Pros:
Under the Oaks DGC is located in a park that is really close to the ocean. In fact, I think it backs up to part of the coastline. In any case, there is salt-water visible from the course which I think is pretty cool. Even with this location, there are concrete tee pads which seem to be in decent condition. Baskets are also in good condition.
For a 9-hole course, this is a tough place to play. There are some birdie opportunities available, but there are also some definite bogey holes. Though I would classify the course as open, there are a significant number of mature trees to provide obstacles. The shade is amazing given the location. I have yet to find another place, just off the coast that provides the canopy found at this course. I understand that this park could only contain a 9-hole course, but I wish there were 18.
Open courses typically allow the player to have options off the tee, which I like. However, I also like it when each player is almost forced into executing a similar shot every now and then. Under the Oaks does a great job of providing this aspect. Most holes give you the option of finding your own line, while others clearly indicate the designed line.
Cons:
My only con is that the course is only 9-holes. I want more. Since I travel and play a lot, I design my ratings based on whether or not someone should go out of their way for a course. It is so hard to recommend that someone go out of their way for 9-hole course...no matter how good it is.
Other Thoughts:
The design here is really, really good...especially for most 9-hole courses that you come across. As a general rule of thumb, I begin the rating for a 9-hole course at half of the standard scale. The reason is that I generally believe that most 9-hole courses are a waste of time. They typically fall into 2 categories: courses to introduce new players to the game, or old courses that were never popular enough to be expanded to 18 holes. Neither type is typically attractive to me. Under the Oaks breaks the mold in that it is 9 holes because of geographic limitations.
If this were an 18-hole course with similar design on the back, I would give it a 4.0. I think it is that good. As is, it is currently the best 9-hole course I have ever played, which is not too shabby. If you are vacationing in PCB, then definitely give this course a shot. It is a little bit of a drive from the tourist beaches, but worth the trip from there. As I stated earlier, I simply have a difficult time encouraging other users of this great site to go out of their way for a 9-hole course. But if you want to give it a shot, then great. It is a nice little spot for a course.
