Since your homemade raft probably won't fit in the bathtub, the next best option has to be the East River, right? The Fire Department's Marine Unit 6 rescued an 18-year-old from the river near 87th Street around 6 p.m. Firefighter Michael Krochak told NBC New York, "We witnessed a person in the water struggling, hanging on to a life ring supported by a rope over a sea wall 40 feet in the air off the East River Drive. That was the only thing he had for support at that point."
Apparently the man's raft "deflated" and he was left in the cold water, estimated to be in the 40s. While MyFoxNY reports, "It is not clear why the man was rafting in the water on a poorly made inflatable raft," fire officials told NBC New York "it appeared the man was attempting to test out a homemade raft." Here's video of the rescue:
The man, who was described as "coherent" upon rescue, was brought to New York Hospital for treatment.
