"David Clark’s life sure has changed. Just about four years ago he was a high school drop-out, making boxes for beer at the Coors brewery in Golden, pulling in about $10 an hour. 'It was really manual labor, it was hard work, and I felt I wasn’t reaching my potential,' Clark said. So he enrolled at Red Rocks Community College, excelled in his courses, and got into Colorado School of Mines. And he graduated earlier this month as a petroleum engineer, walking right into a job that will pay him more than $100,000 a year."
