Well not that kind of sports fan, I mean, not a huge fan at least, but my teams (more internationally than it should be but..) in Venezuela the Baseball is pretty much the sport everybody loves, so my Local team is Navegantes del Magallanes (Magallanes's Sailors).
Soccer (Futbol) from Spain El Barça or Barcelona.
Hockey, honestly here are some places where the whole year has frozen temperatures, but I don't know a single place where you can play it.
I don't follow any particular team on action or extreme sports, but that's what I like the most
which sport do you think will be better to watch in a HMD and why?
