The Today Show's Al Roker talks about his book Ruthless Tide: The Heroes and Villains of the Johnstown Flood, America’s Astonishing Gilded Age Disaster.  He discusses the elite country club that compromised the structural integrity of the South Fork Dam causing the flood, he reveals some of the famous industrialists who belonged to that club, and how they escaped justice for the Johnstown flood in a notorious trial that ultimately led to important changes in US liability laws.  Plus Al Roker relates the lessons of the 1889 flood to global climate change and America’s modern day infrastructure needs, and on a lighter note, the self-described BBQ aficionado offers a few summer bbq tips for the grillmaster in your family.
