We went to Barclays Ctr. to see the RHCP. Being that it was superbowl weekend I thought it was going to be chaotic. It was so organized. We got right in and security was great and the workers did a great job. We drove in because I was with my teenage girls and didnt want to ride the train or subway alone at night with them however, you can get there by train to Grand or Penn and then take a taxi to the ctr (about a 20 minute ride) or just take the subway in and get off right in front of the Barclays Ctr. We had nosebleed seats for the concert but it wasnt a bad seat. The bathrooms were so clean and the lines werent long and they just were so organized. Driving in wasnt bad either. I thought it would be much worse but it really was not hard.I definately would go there again. And I thought Brooklyn was beautiful. It is NYC in a different way.
