It took guts for David Roach to stand before the Barton County Commission Monday morning. The 55-year-old Great Bend man has had his share of problems with drugs, alcohol and the law over the years.But, he said, he is clean and is now a role model for his granddaughter. He attributes his success to his being a part of Central Kansas Community Corrections which supervised his parole.In the past year, CKCC has served 105 parolees.
