Terry,
I agree with you about #13 at Flossmoor. They took out the worst hole on the course and had the opportunity to build a truly great par 3 from scratch. They built an OK hole. The green is OK, maybe a little large for a short hole, but I do like the run off area. They should have added a unique feature like the near doughnut greens like #6 at Yale, 17 at Piping Rock, or #10 at Chicago.
I used to joke that the old 13th was Flossmoor's Redan.
