It's not verticutting. With 600 members, substantial guest play and at least 100 kids in a junior program, that range gets a lot of use. That said, it is usually in fairly good shape.
Medinah is and always was a big club. It has family events, tennis, swimming, junior camps, junior golf and organized member events most every day from May 1 to October 1. After October 1 to April 30th, it is constantly hosting big holiday celebrations, kids Halloween parties, Christmas parties, gun club use, gun club parties, etc.
If you're expecting Medinah to have the tranquil feel of an Augusta, SFCC, Pine Valley, etc. you're going to be tremendously disappointed. It's an active club and its facilities gets used.
