I started worrying about Lava three years ago. That's when the Park Service reshuffled its Grand Canyon river permit system, and we were able to move our launch date from "someday maybe" to Summer 2011. A good time: my son would be graduating from Durango High School a month before we put on, and head off to college a month after we took off. A perfect rite of family passage for a family raised in large part on the river.
