So many things to do in Brooklyn. You could go to the Greenwood Cemetery to visit Jean-Michel Basquiat's grave (or the original Murder Inc. gang members graves), the Brooklyn Botanic Garden (no buds though), Brooklyn Boulders for some indoor climbing or some genuine fun at Coney Island's Luna Park, etc. 99 things!
Now if you tell me that you're bored in Brooklyn, I don't know what I can do for you (I could slap you though).
