In New York City, professional sports is as popular a conversation topic as pizza or the weather. Home to some of the greatest dynasties and underdog stories alike, we'll tackle three boroughs this week to visit their home fields. We start at the Barclays Center to visit the Nets and Islanders, then cross the Manhattan bridge to visit "The World's Most Famous Arena," Madison Square Garden, home to the Knicks and Rangers. Next is a long walk to the Bronx to visit the world's most successful professional sports franchise, the New York Yankees. We conclude with a trip to Queens to visit those lovable losers of Citi Field, the New York Mets.
