Welcome Bob, I look forward to hearing more from you in the coming weeks, months, and hopefully years. This place just keeps getting deeper and deeper with knowledge (or some might say just "deeper" with something else).
I played Flossmoor back in May 2011 after your work. Unfortunately not being from that part of the country I had never seen it before, but I was impressed with the finished product. Also given that several other courses in the area were borderline flooded I can say that whatever you did drainage wise was a success. The course was in great shape while other courses in the neighborhood were inundated.
I hope to get back up there again sometime, and I also look forward to seeing posts from you in the future.
Again, welcome to this nutty bunch!!
