Vegas arenas vs Brazil

Seems like a good amount of fighters gassed and I'm left with wondering where it is that this UFC took place? High elevation or just awful AC? I mean Vegas is hotter than blazes but seems like the temp is well regulated in the MGM and Mandalay. Thoughts? Phone Post

Brazil's building doesn't have ac either, I think that played a big factor. That many people in an enclosed environment in Brazil would be pretty damn hot. Phone Post 3.0

Seems asinine to host fights in conditions like that when there's so much on the line. Phone Post

Holding an event of UFC caliber in a venue without AC seems careless Phone Post 3.0
