Puerto Rican fans are superb,as are Mexican fans. I mean Mexicans follow any/all of their fighters with a passion that is hard to match. I'd alos like to nominate Manny Pacquiao fans,the noise when he enters an arena is amazing(watch the Morales fights) and the fact that SOOOOOOOO many peeps fly over from the Phillipines to watch him fight Stateside is amazing! I find the fans who have travelled the furthest are the loudest!
