I can understand the NC folks getting irritated - they've put a lot into their courses and are getting ready to host what will probably be the best tournament ever held.
For whatever it is worth, speaking as the course designer, I honestly don't care what anybody thinks about Renny or any other of my courses. I don't invest my time and energy for affirmation from other people. I am not irritated at him or anyone else who does not like a course. Play on!
