No, Vegas is the place
The IFBB are nuts to continue with a formula that doesn't work. Only a few years ago, the Mr O was held at Mandalay Bay, now it's held off the strip because they couldn't get the numbers.
It was better in the 90s when they moved city, year by year. A much better atmosphere too when your see the Youtube clips of people blowing horns when Dorian dominated.
Only thing against moving it would be that most competitors would be getting stopped at the airports for trying to smuggle their diuretics through.
