I know people who groan at the idea of driving cross-country, and when I say, “have you done it?” they say, “yeah, it sucked”. I ask how they went, and they took I-80.
80 is direct, sure, but it’s awful. There are huge numbers of trucks, and construction, and random slowdowns that don’t seem due to either trucks or construction.
But I-90….oh, 90 is nice. Zooming along at a high speed through the wide-open West. So nice. And it’s got great detours.
