Greenlefe was a place that my dad, uncle, and I went back to for a couple years running back in the late 90s to play right after Christmas for a couple days. It fit the bill, and played a small part in my early architectural education as it was so much different from what I was used to in the Boston area.
I remember the West being a pretty good championship test, the East was too narrow, and the South was full of large sandy waste areas, which gave it its own feel. We branched out to Diamondback across the street right after it was built, and it was very jungle-infused. The highlight was the massive stuffed rattler in the temporary clubhouse.
Amazing that it held on until now, as it was clearly in decline as of our last visit in 99/00 or so. I think it first went bankrupt in 2002.
Great Southern seems like a loss for MS golf history...always wanted to check it out but never made it to that corner of the US.
