Pros:
An accessible course with good basic offerings.
-Amenities: Concrete tees. Mix of Prodigy and Mach III baskets for the two distances. Detailed tee signs at every tee, which also have little gold stars to mark current pin placement. Taped spokes and next tee signs around as well. Bridges over low-lying areas to keep feet dryer.
-Multi-Tees/Pins/Baskets: Two tees per hole, with two baskets per hole, and most holes also have multiple pin placements for both the long and short baskets. Blue to blue (longest) is a solid intermediate challenge with usually over 300' and some trees to go through, while red to red/grey (shortest) is significantly easier.
-Shot Shaping/Gameplay: Good par-3 offerings with a steady diet of loosely associated, mature trees. Not a bombing-type course, but every basket has multiple plausible lines and requires good speed from the longer tees. As a rec player topping out at 320' I barely had birdie opportunities from the blue-to-blue configuration, but that was probably an error in tee selection. The creek was used nicely at the end of the course. The par-4 was nice, but none of the holes really stood out to me except perhaps the 410' par-3 on (12), which for me was a fun two-shot hole with a thoroughly-guarded green that requires drive placement.
-Playability: Frog Rock is open enough that it's hard to lose discs, but also shaded from Georgia sun. It's also well-kept, so really no environmental hindrance to playing.
Cons:
So much of the same theme.
-Repetitive: There is virtually no variation in terrain or style at Frog Rock. Though the reasonable-length, moderately-treeful shots are good, it's the only kind of shot you'll throw from the tee all day. Yes, there is variation of straight/left/right and some variation in shape, but there's so much flexibility that by the time I got to (7) I was already a little antsy for something different, which I never got (other than the par-4 hole (8)).
-Navigation: There are often multiple tees in sight from the basket with little indicating which is the next one to go to. You can figure it all out, but could very well take extra time hopping from pad to pad.
-Drainage: Not a lot of elevation change here, so water can pool in certain parts of the course.
-Safety: There is a walking path you'll probably have to stop for. Depending on how busy the course is, you'll also need to be aware of golfers on adjacent fairways.
Other Thoughts:
Frog Rock is one of the least diverse 18-hole courses I have played. However, its basic theme is quite good for rec and intermediate players, and friendly to newcomers to the game. It feels like a 2.75 course, so for now I've followed my rule of rounding towards the middle. It's one of those Typical courses that's plenty of fun but nothing spectacular.
