How soon can u bet in Vegas?

my Step Brother leaves for Vegas on the 19th of Feb, and said he'd make a bet on the UFC if they're up. I was wondering if they'd have some of the fights from the April card available to bet on by then?

highly doubtful they'd be up already.

They won't be up in Vegas until days before the event. Offshore books are the only onbe's that carry theearly numbers.
