Doing a couple of hours of research, here is a list I put together of what closed (incomplete):
Walnut Hill Columbus Ohio
Dogwood Hills Golf Club South Carolina
Crooked Tree Golf Course Mason Ohio
Escondido Country Club San Diego

Most of these are older courses, a common theme seems to be that with the number of rounds down, the land is just too valuable to remain a golf course.
