Ran: I did a little digging for you re: Chicago Golf's greens. However, I don't know where they rank in terms of total size for a Raynor/Macdonald course. The total size is 129,624 square feet (ave. 7,201) for the greens. The total for the approach areas is 18,246 (ave. 1,014). The largest greens are #7 (redan) 9,758, #1 9,048, #17 7,955, #11 7,829, #15 7,744, & #6 (road) 7,740. hope this helps. Pete
