I think Oak Hollow is definitely worth a play, but only if you're in the area. As others have noted, it is a fun track, with quite a bit of quirk. It's a great look at an early Pete Dye design, railroad ties and all. The course is quite short (probably only 6400 from the back tees, par 72), and conditions can be spotty. Though I've played it probably 2 dozen times, I can't remember every hole on the course (it's been at least 2 years since I've been there, and I'm not one of those guys who can remember every hole). No. 1 is a short, fairly non-descript par 4. No. 2 is a short (very short?) par 5. It's easily reachable in two, but the green is tucked up on a knob, with a couple of trees and the angle of the green creating a challenge to get home in two. The holes on the lake are strong, along with number 10, a lengthy (by Oak Hollow standards) par 5. Some holes are too quirky for my taste, like number 8 or 9, which is a short par four, very up and down fairway, lined with railroad ties. If you've never played it before you'll definitely hit your drive in the wrong place. The landing area, up the right side is quite small. Anything hit in the middle or left side falls off to oblivion.
As others have mentioned, it's a great value. I've only played on weekdays, and during the week you can walk for about $12 or $15.
