It's not a tree that grows in Brooklyn.

This time, it's an arena.

For many longtime borough residents, the Dodgers are a team that has always played in Los Angeles, and they're too young to remember when Walter O'Malley moved the beloved Bums to sunny California and broke Brooklyn's heart.

The Dodgers were the heart and soul of Brooklyn. Many players lived there year-round, rode the subway to Ebbets Field and read the Brooklyn Eagle.

But now, Brooklyn has a new arena and a pro sports team, the former New Jersey Nets. From a personal standpoint, it's ironic that the Nets have for the past few years played in the Prudential Center in downtown Newark, an arena where our nephew does the scheduling.

So Brooklyn is big-league again, and I'll let the Associated Press tell it:

NEW YORK (AP) - After decades without a professional sports team, New York City's ascendant borough is hitting the major leagues again on Friday when the Brooklyn Nets' new arena opens to the public.

The 18,000-seat arena will be officially christened Saturday night with a rap concert by Nets co-owner and native Brooklynite Jay-Z.

The opening of the Barclays Center is a symbol of Brooklyn's astonishing rise in recent years as a sought-after destination for people from all over the globe.

And it's vindication for old fans of the Brooklyn Dodgers, the baseball team that fled New York City in 1957 for Los Angeles.

The city is banking on Brooklynites' deep-rooted sense of borough pride to win over new Nets fans.
