I've been to a few places where bad things have happened. I was at the World Trade Centre in 2001 a few months before the attacks. I've been to the site a few times since. I've been to Auschwitz and Dachau concentration camps and I've roughly stood under where they think the atomic bomb detonated over Hiroshima. I've been to Pripyat and the Chernobyl Nuclear Power plant. I've had lunch at the power plant, food wasn't great. All sobering experiences in their own way.
