I lived in GA for 40 years, drove by Butternut many times, but never played it; wish I had.
Out of curiosity, how is Old Union now? I played there many times, and loved the layout, but I know there have been struggles with conditioning over the years. Also, I think at one point Denis Griffiths, the GCA of Old Union and a bunch of other good courses in GA, was the owner. Don’t know if that’s still the case.
