New Yorkers always put their stamp on things that belong to them - there is always something more that an outsider might not figure out. There is always a little something extra.
Example: Mermaid Day
Every big city has parades. Everyone everywhere has seen the Macys Thanksgiving Day parade on TV. But some things that happen in NY aren't so suitable for TV but are still very much NY. Take "Mermaid Day" for example. Every June Coney Island has a huge parade that "celebrates the sand, the sea, the salt air and the beginning of summer, as well as the history and mythology of Coney Island, Coney Island pride, and artistic self-expression."
The Parade is characterized by participants dressed in hand-made costumes as Mermaids, Neptunes, various sea creatures, the occasional wandering lighthouse, Coney Island post card or amusement ride, as well as antique cars, marching bands, drill teams, and the odd yacht pulled on flatbed.This past year people used the parade as protest of BP's efforts with the oil spill (oil leak in this parade) as well as using metro cards to make art and costumes.
