Meet the man who turned off the American Falls.
Col. Amos Wright is a retired US Army solider and engineer. He and his wife Gloria live in Provo, Utah, where he spends time perfecting his golf game.
“It’s a pleasure to get out and be able to get out,” he said. “I claim that I can shoot a score below my age but you have to be pretty old to be able to do that.”
He’s actually 92 years young. In the late 1960s he was with the Army Corps of Engineers in Buffalo. As the district engineer, he led a project to shut down the American side of Niagara Falls.
