The day we rolled into Tennessee was day three of our road trip from Ciudad Juárez to northern Virginia. As we checked into our Knoxville hotel and unloaded the cars for a third night in a row, we’d crossed nearly 1,500 miles (or three-quarters) of the trip and expected to make it to northern Virginia the following day.
I’d been living in the mostly dry warmth of the desert sufficiently long to use my weather app infrequently, although our last week in Juárez had been marked by infrequent sprinkles. But because Knoxville’s temps were dropping below freezing, we glanced at the forecast and realized we might need to slow our roll.
