Prairie Club (Dunes) - I really wasn't sure what to expect. I was blown away. It's in my personal Top 2.
Erin Hills - I thought I'd probably like it but not love it. I loved it.
Idle Hour (Lexington, KY) - I knew it was good, but had no idea it would be as good as it is.
Dark Horse (Auburn, CA) - About as much fun as any course I've played.
Waveland (Des Moines, IA) - I expected a dump. It's actually a really cool course on a fantastic property, even if it does need a bit of napalm. And I guess it is a dump as far as conditioning is concerned. But I loved playing there when I was working in Iowa and would love to see it with a bigger conditioning budget and a lot of jungle vegetation clearing.
