Has anyone met Mitch Albom before?

Yes,I have. He was very personable but the amount of time will depend on the line. I suggest going with a friend and putting one of you in the front of the line and another toward the back. Bring something to set you apart-nothing big just a little something-then join your friend in line after your first time through. When you get back to the front remind him of the item and say you just wanted to see him again and try to get a photo. My impression is that he will accomodate you if he can...Get an autograph for sure!
