WELLFORD, S.C. (AP) — Aaron Hill knew the road well, and not just because it was the route he took to high school every day. The five-mile stretch of highway was named in memory of his father, a soldier killed by a roadside bomb in Afghanistan in 2008. But on his way to class Thursday morning, the 18-year-old senior was killed when a pickup truck crossed the center line and smashed head-on into his car, authorities said.
