I saw Dave Draiman from Disturbed in Iowa on Monday night!!! We were eating out at 801 (very expensive steak house) for business. I look over, and about 10 feet away from me in a booth was Dave. I didn't talk to him because I didn't want to bother the guy while he was eating dinner.
The funny part was that I was sitting there, and I know it was him and not some guy trying to look like him. My first reaction was "I've got to tel somebody", and I did tell the others at my table. The sad part is that I'm telling to to a group of people who are all older than me and have obviously never heard of Disturbed. It was kinda funny, because one of the girls did know of Slipknot (they're from Iowa).
I think if I would have gone over by him he'd have gone 'Who the f' are you?", seeing as how I was dressed in khakis and a polo shirt and very dada looking compared to my "cool" days

On a side note, I also ran into Brian Urlacher at the Shed Aquarium a few years ago.
