The poem ends with this:
"There is a place called Colorado where you will,
Of course, be very glad to arrive, where the others
Wanted to go; and you will sit smug in the shade
High up on a mountain, feeling the wind
Send shivers over your body, looking back
At the great sickening swoop of the plain
And think it part of a grand design:
Satisfying, necessary, even beautiful. "
