As a kid I remember having a crazy thought once when I rolled up to a stationary basketball just lying there, "I wonder if I can whack this with my front wheel and send it flying..." That thought ended with me on the ground and the ball basically laughing at me so like many thoughts I had during childhood (and adulthood for that matter), I never thought about it again.
Dead Horse Bay in Brooklyn, NY is not the beach you go to for a day of sun and swimming; it's an awesome time capsule full of garbage treasures. Please don't go swimming in the water.
