I would love to see Old Barnwell. From what I've seen in photos, it looks like they've done a great job of blending interesting, varied golf, with some victorian era features, and also features that you might see on a Braid course. I love the look of the 16th green. Most great modern courses now try to hide earthwork and make it blend in to the surrounds, which is great. But I do like the idea of being intentional with not doing that to achieve a different look or feel/play.
The Lido is an obvious one, and I'm hoping to get there in the next year or two.
I'm also excited to see Cabot Highlands. A new course in Scotland is always neat, and it will be wonderful to see what Clyde can do as Lead Associate. I know how funky he likes his GCA, so I fully expect some quirk and fun in there.
