Or at least, Utah is shrinking.
The exits from Interstate 15 are numbered according to how many miles they are from where I-15 enters Utah from the south. So, for example, since the Lehi exit was marked as #282, that meant it was 282 miles from the border with Arizona (as the crow follows the Interstate.)
But the Lehi exit was recently changed from 282 to 279, which means it is now only 279 miles to Arizona — three miles less than it used to be.
Thus, Utah must be shrinking.
Of course, the government doesn’t want to start a panic, so it has a different “explanation.”
