Finally, a use for texting that doesn't involve sexting, car accidents, or acquitted rapists: A teen and his grandfather were literally trapped in the mud Wednesday night when their canoe capsized after duck hunting in the Hudson River's Tivoli Bays. Thomas Mulvaney, 17, and Christopher Hoffman, 73, were dripping wet and stuck without a way to get out, and their phones weren't able to make calls. But Mulvaney was still able to text for help, and they were saved after three hours. The Dutchess County sheriff's office said the pair "started to have the onset of hypothermia. There was a definite risk of life-threatening issues," while Hoffman said, "Without that cell phone of his, we would have been in deep shit."
