Hi Don - Hope everything goes just fine with your surgery tomorrow. Take some deep breaths and try to relax. Write down whatever last minute questions you have. When my son had his surgery, we had to be there very very early and there was a lot of waiting and paperwork to take care of. He brought his camera and had us take pictures while he waited! Bring someone with you, if you can - it helps with de-stressing. I used to live in Chicago for about 20 years. Lots of nice people there. Give us updates whenever you can!
