At 8:30 in the morning at the Crystal Café, the sour cream raisin pie comes out from the kitchen too hot to slice. At the counter and in the booths, men and women who are starting the day (and some finishing a long night) converse about issues that include jackknives, deadheading, log books, and speed traps. They are professional truckers; the Crystal Café is where they come not only to eat, but for fuel and over-the-road supplies. It is an open-all-night truck stop just west of the Missouri River.
