Safe and warm in Fayetteville

When I woke up yesterday morning, I probably should have stayed put, at least according to the Arkansas Department of Transportation.

I don’t have much experience with winter weather, but the agency’s online map just before dawn looked like the back of a loom, with a complex spray of colored lines indicating which roads were covered by ice, which roads were covered by snow, and which roads were impassable because cars were already piled up on them.
