Campbellsville Elementary School students, teachers and administrators are raising money for cystic fibrosis research.
On Halloween, students can pay $1 to wear their costumes to school.
All money collected will benefit cystic fibrosis research, in honor of the late Kelsi Brown, who battled the disease.
Brown, a niece to CES bookkeeper Patti Caulk and CES special education teacher Libby Caulk, attended Campbellsville Independent Schools several years ago.
Students are asked to not wear masks or bring any weapons to school.
For more information, or to donate to the effort, call the CES office at (270) 465-4561.
