I just did a quick count, and since originally posting roughly a year ago, I have played 35 courses in/around Columbus. I have fun playing almost anywhere, especially with good folks, but gca-wise, my favorites so far include: Brookside, Granville, Hickory Hills, Pinnacle, and Columbus CC. Champions, Longaberger, Clover Valley, Cook's Creek, and Darby Creek are also fun ones (and all public). I have walked Muirfield (memorial), Scioto (US Open qualifier), and recently caddied 38 holes at Double Eagle (as part of gca member Brian Laurent's Hundred Hole Hike) and found each one impressive in different ways. Looking forward to actually playing Scioto in a few weeks, to see if I enjoy it as much as a player. I still have not seen The Golf Club, but my informal (but extensive) poll of local golfers tells me it is the best of the bunch, which is perhaps no surprise to many on this site.
To the extent that there is interest, I would be happy to help organize a get together this fall in Columbus. There are certainly plenty of courses from which to choose. If nothing else, it should be on the short list for a future Midwest Mashie.
