DAYTON, Ohio -- A few minutes before 8 a.m., the clouds in the October sky hint at a downpour any second. But auto dealer Jenell Ross and her team of some 200 friends, family members and dealership employees aren't about to let the threatening weather dampen their spirits. They are among 10,000 people preparing to walk through downtown Dayton to raise money for the American Cancer Society's efforts in breast cancer research and education.
