Fight fever insanity hours before #MayPac

It is fight night in Las Vegas.

With bated breath, the whole world awaits the fight of the century.

Who will be the king of the ring – carpenter-turned-congressman Manny Pacquiao, or the high-rolling former Olympic standout Floyd Mayweather Jr?

Fight day is finally here and there's no other place in the world where fight fever is at its highest than here in Las Vegas.

Today is May 2 - Floyd Mayweather Jr and Manny Pacquiao will face off in the ring to decide once and for all who the best pound for pound fighter is today.

Sin City is bustling with fans decked out in shirts and caps announcing their picks.  Security is tight. And people are trying to get last minute tickets to the fight of the century.

Stores are selling out on merchandise. This is the biggest fight Vegas has seen ever and fans know it.

GARY COATS, MAYWEATHER FAN: I'm from Brooklyn. (Why are you rooting for Mayweather?) That's the Money Team. That's where it's at.

BRANDON INGRAM, PACQUIAO FAN: I got this shirt on eBay. Good guy. It says everything I feel about Mayweather. (Why are you picking Manny?) Because he's going to knock him out.

Roads and hallways are filled with people. Even closed circuit tickets are sold out at some places, with everyone wanting a piece of hustory

By the end of tonight some in this crowd will be less happy than they are now. Will Mayweather get his first defeat or will Pacquiao, like the 47 others, fail to put Mayweather down?
