I think Heath was working in the ring while I was doing the BJJ class. I'm pretty sure it was him but not positive. I didn't want to be the guy going "Whooaa is that Heath Herring?!?!?". If it was him he looked like he was doing fine and I certainly wouldn't want him to be hitting me.
I don't know how far the place is from the Imperial. I was at the Golden Nugget and their school in Valley View was about a 15-20 minute drive in light traffic.
I also met Phil Baroni in the casino at my hotel. On this occasion I WAS the guy going "Whooaaa are you Phil Baroni?!?!?", then I got my wife to take photo of me standing with him. Contrary to the persona they show on the UFC he came across as being soft spoken and very friendly.
