The Golf Center at Kings Island, the course Jack Nicklaus mentions in his feature interview, was an 18-hole facility (never mind the executive course attached to it) that, to my knowledge, is the only course to have regularly hosted a PGA, LPGA, and Senior PGA tour stop. Sometime in the mid-90s a third nine was added by Jay Morrish, and some fairly nice homes were built up around this new nine.
Owner Carl Lindner (who used to own the Cincinnati Reds, among many, many other pursuits) then sold the entire facility to the city of Mason, OH. The city then sold off a few separate chunks of the 27 holes for development, and what is now left is 22 holes and no driving range. Additionally, it's never in the shape it used to be in. It's a shame...I guess the lure of big bucks was too much to overcome, and as a result a once-fantastic golf operation is kind of a shell of its former self.
Also, Shaker Run Golf Course in Lebanon, OH (site of the US Publinks maybe 10 years ago) added a third nine at some point. I don't care for the original golf course, so I haven't been there in a while and can't speak to the new nine.
