I can give you, off-hand, no details of the planned introduction of cellular phone coverage in Yellowstone National Park. But there is a culture-war over the future of The Park - with respect to just that introduction. The details of the introduction are relatively unimportant. It is a matter of governing principle. And where principle, then competing principles.
The principled war may be described as being over the proposition (acceptance, and rejection, of which signals... attitude, character, life style?) that: (U.S.) National Parks ought to offer us the experience of a different space - therefore one in which automobiles, cafes, roadways, signage, industrial noise, wires overhead, hours o'clock and, yes, cellular phones in use, were nowhere to be perceived (or, at the very least, were extremely compromised). What the corollaries of this proposition suggest is that the war is also over the proposition that: (U.S.) National Parks ought to offer us the experience of a different time.
And this is one of the magical things about the U.S. National Parks. They transport us (and ought to do so) - not, merely, to a space which is different (especially as regards what occupies it in a specific mode and, so occupying it, thereby creates the genre of space occupied), but - to a different time. The more successfully a Park does this, the more obvious it is that the time it has transported us to is significantly similar to the past time of just that place. We like time-travel (or the nearest we can get to it in actual-world time) as much as space-travel. Indeed we do! And, dear me, the magic of socialism to be able to afford us such luxuries! (Time-travel, by the way, comes with impossibilities - the impossibility, for example, of contacting Madison Avenue or Wall Street on a whim.)
The introduction of cellular phone service into valued, if only budding, past-time is an abomination. There's religion for you! That introduction attacks the different space that National Parks ought to provide (as regards what that space contains), but it more clearly attacks the difference of time that National Parks ought to provide.
We need to make explicit this proper Originale motif (okay, okay!..., this pretty good Somewhat Earlier-motif) that - put in place - would rightly govern National Park policy. If some such regulative-motif were to preside, cellular phones would be (almost entirely) absent from the Parks.
And it would be both lovely and correct.
