I’d never seen pigs transported on an interstate highway before Aug. 22, 2015. We had visited family in Valdosta, Ga., and then went south again to Gainesville, Fla., to visit our daughter at the University of Florida. While driving home, I was riding shotgun when we saw this sight: a truck pulling a trailer with pigs in it. It was south of Gainesville on Interstate-75. The blur in the image at the bottom left is my reflection in the glass.
