From a New York Times obit by Alex Traub headlined “Greg Wittine, Once a Hero for Disabled Boy Scouts, Dies at 67”:

Greg Wittine had a severe case of cerebral palsy. He could not walk or talk. In his wheelchair, he carried around a homemade keyboard on which he would point at individual letters and spell out words in order to communicate.

He devoted his youth in suburban Long Island to the Boy Scouts. Over nearly a decade, he earned merit badges in subjects like fire safety and wildlife. To get his hiking badge, he crawled down a wooded trail for a mile until his knees were too bruised and bloody for him to go on, at which point he wheeled himself another nine miles.
