The aquarium itself was fun. We saw a sea lion show in an aqua/amphitheater, and spent probably two hours seeing penguins, walruses, jellyfish, sea horses, sharks, rays, and all sorts of colorful fish and sea life. At one point, the girls sat on the floor beside a jellyfish tank and drew pictures in their books. But there were several youth day camps at the aquarium and no room was empty for long. We even made it past the gift shop without buying anything!
Up next was a visit to the beach at Coney Island, something Bella's dad was not prepared for. But we did have sun screen. So we avoided broken glass in the sand, made it to the shore, Bella stripped to her underwear and got slathered with sun screen. She had fun in the six-inch waves, digging in the "sand" and dipping her fanny. I even took a photo of her that looks like she's surfing. But it was hot and we were hungry, so we dried off as best we could, got dressed, and hit the boardwalk.

The boardwalk at Coney Island is 100% crazy, hence the new name: Crazy Island. The kids made it as far as the first amusement park, stopped at the entrance, and took in all the rides, colors, people and music. Bella, of course, felt the music in her soul and couldn't help but show it (though the video was taken after the real bumpin' song was over).
We made it to Nathan's Hot Dogs, ordered more food that any human should consume from that place unless there is a large sum of money and mustard-colored belt on the line, and sat down in the only shade available - right outside a public restroom. We ate, and ate, and took in the rides we could see over the strip of eateries. Then it was off to an amusement park where we bought a $25 pass good for 10 rides, and the Bella and Sophia rode two little kid rides - the whale ride and the choo choo train - and Tamara and her friend, Noah, rode a bigger kid roller coaster. Then the kids reluctantly left, and Sophia's mom and Bella's dad relished the air conditioned train ride home.
For people watching, there is likely no better place that the boardwalk at Crazy Island. Yes, any street in New York City is prime real estate for such expeditions. But I've rarely, if ever, seen such a concentrated mass of cross-generational, global and pan-economic display of humanity. There were well-to-do older Italian type couples strolling in black linen suits, grubby teenagers with multiple piercing, tattoos, and dumb shirts, Asian families, groups of young men from Europe, drunks, sketchy old dudes sitting around, carnival barkers, kids with attitudes as large as the Cyclone, and women with not enough bathing suit on. I could sit there for hours - in the shade - and never be bored.
So, Crazy Island, we'll be back. And next time, we'll be ready for you.
