At a certain location in Havana's Central Park, you'll see a group of men standing around arguing ferociously. Sometimes they almost appear that they are going to bring out weapons and start killing each other, the conversation gets so emotional. What are they arguing about? Politics? Religion? No -- baseball. La Esquina Caliente (the hot corner) is a longtime Havana tradition, where men passionately argue and debate the finer points of Cuba's national sport.
