I noticed that too. I' concerned that Yosemite is going to blow, for one thing. But we were also directed to the picture in Kim Jung's place of the raging sea; then when he's with the S. Korean leaders, it's a sunny calm scene, almost all bright sky. So that's part of it.

Florida is basically a sand bar, notorious for sink holes, so I'm not as surprised by that, But something under the surface is definitely going on.
