The annual Alma Chalk-The -Walk project is expanding to six days. Sponsored by the Alma Action Association and Alma Community Art Center, teams of from two to five members are invited to create designs on four-foot by four-foot sidewalk squares downtown on Superior Street. During its first three years Chalk-The-Walk was a one-day event. This year, however, it will run for six days beginning Saturday. There’s no cost to take part. To register, call the Art Center during business hours, which are from 11 a.m. to 4 p.m. today, Wednesday and Thursday.
