Yeah, there are many better options than Heather Glen in MB, even just in the North Carolina/Little River area of the Grand Strand (I prefer Thistle, Glen Dornoch, Tiger's Eye, Leopard's Chase, River's Edge, and Oyster Bay just off the top of my head). It's not somewhere I ever actively wanted to play; it was usually a fall back option when we couldn't get a tee time somewhere we preferred. But the fact remains that among courses I've played within an hour or so of Atlanta, I'd say only the Frog and Achasta are clearly better courses than Heather Glen, and neither of those courses are within 30 miles of the city.
As far as Ocean Ridge -- I think Leopard's Chase and Tiger's Eye are both really good golf courses, and Lion's Paw and Panther's Run are solid. But the last couple of times I've played there the conditions were really bad. Weeds growing in the fairways, dead areas on the greens, etc. Leopard's Chase and Tiger's Eye used to consistently be in excellent shape with the other two courses hit or miss, but recently it seems like they've significantly cut the maintenance budget on all four.
