I don't know if this has been posted somewhere else or not, but ran across it today at my old stomping grounds... getting ready to make my next check-up appointment at Midwest Orthopaedics at Rush... He's not my doctor, Dr. DeWald is now that Dr. Hammerberg is full time at Shriner's now.

Anyway, I thought I would throw it out there.
