Best crowd I ever experienced was in Cancun, Mexico, for what should've been (but unfortunately wasn't) Shane Mosley's last fight.
Ninth round against homeboy Pablo Cesar Cano, Mosley's tired & getting outboxed, suddenly he lands a big left hook & Cano wobbles. The crowd (locals to a man/woman/urchin) stand up as one & a couple thousand people start chanting in unison:
"A-Zoo-KAH! A-Zooo-KAH! A-Zooo-KAH!"
Took me a second to work out that that was Spanish for "Sugar" (or, you know, the phonetic rendering of same).
Mosley came back & won the fight. Fuckin' loved it.
Boxing crowds: you can be partisan, fucked-up, even racist at times. But sometimes, the love of fight people for fighters shines through & then it's all fuckin' gravy.
