He's asked about Las Vegas being his home-away-from-home and he responds saying that most people go to Vegas for the fights, they don't necessarily live there. So the crowd will be full of people from Hawaii, Canada, all over the US and even the world.
I agree with this. I used to live in Hawaii and know that Vegas is probably the #1 vacation spot for people in Hawai'i. Also the largest concentration of Hawaiian transplants is in that area of the country (California, Oregon, Vegas).
