SHIPPENSBURG, Pennsylvania — Chet Eby is making sure you are going to get all of the bacon you need for breakfast, or maple-glazed ham for that now-modified family Easter dinner you are going to make, or that thinly sliced prosciutto and provolone sandwich you’ve been craving. It is a Wednesday afternoon, and the 31-year-old has his young sons, Austin and Evan, with him hauling a load of piglets from Cumberland County to Iowa, one of millions of road warriors behind the wheel of a truck traveling across the country every hour of every day making sure the food and necessities you need and enjoy are available at your local grocers.

“I am hauling baby pigs from where they’re born in Pennsylvania to the farms where they fatten them out in Iowa,” he said from his starting point. He is heading out to Iowa with his truck filled with 20-pound pigs. “So on our end of it with farmers, every eight weeks, a new litter of pigs is born, and we have to get the little ones out of the barn, the barn needs to be empty so the next batch can come.”
