Looking for things to do in Brooklyn this weekend? Here are four tres Brooklyn events you can't miss:

• Sunday head toward the mother of all Brooklyn street fairs, the Atlantic Antic.
• All weekend: DUMBO Arts Festival. Have fun at this arty indoor-outdoor event. Check the schedule.
• Opening Weekend of Barclays Center: It'sopen, with a full week of sold-out concerts (9/28-10/6) by 13-time Grammy award winner, Shawn Carter, AKA Jay Z. If you are going to Barclays Center, take public transit. The mega-stadium is opening and nobody quite knows what a crowd of 18,000 people headed or from to the same place at the same time will look like. Traffic advisory: Unless you have tickets for the opening weekend Jay Z concerts at the new Barclays Center, you probably don't want to be driving around the intersection of Flatbush Avenue and Atlantic Avenue around show time, 8 P.M.(Read reports from opening night.)
