A few weeks ago I returned from an annual sojourn into remote sections of Grand Canyon National Park. With all due respect, I can honestly say that if I saw one of those jet boats blasting through the Colorado River rapids, it would be the last time I visited the park. (That is, until the campaign that I personally initiated saw to it that they were forever banned.)

Of course, if someone wants to accommodate the craft by building an artificial rapid in the middle of some strip mall parking lot (and serve beer to those waiting in line), have at it.
