Mermaid Riverboat Ball

The official after-party for this year's Mermaid Parade is, rather fittingly, a waterborne affair, with Adam the First Real Man hosting and a bevy of bands, DJs, burlesque artists, sideshow performers and go-go dancers (not to mention free beer 6–8pm) adding to the appeal. All ticket purchasers must ride the party bus from Coney Island USA to the boat; for more details, go to coneyislandusa.com.
