Thanks for the link, Donuel. I enjoyed the dolphin.

Whenever I cross the Missouri River, I get to observe its turbulence. The water forms bunches, and it looks as if people have cut brown bunches of broccoli crosswise and packed them into the river. (This is the appearance of jets of water going up and down, rather that going downvalley, the way they should.) The Corps of Engineers has made the River narrower and faster than it used to be, so there really isn't room for all that water in its course.
