Mayor Darryl Grennell, center, gets ready to lead a group of bicyclists from City Hall to the Natchez City Cemetery and back as the kickoff of a program to encourage local residents to exercise. The mayor kicked off the event one day before an educational summit on diabetes and heart disease that begins at 11 a.m. today at the Natchez Convention Center.
