SANFORD, Fla. — Ahead of Veterans Day on Thursday, one group honored fallen service members Sunday.

The Central Florida Cemetery Project held a cemetery cleanup and placed flags at 350 sites at the Evergreen Municipal Cemetery in Sanford.

Organizers said they needed even more flags and hope to go back.

"They're so important. It's hard to explain the meaning that veterans have for us,” Jennifer Eve of the Central Florida Cemetery Project said. “They truly are our passion. They are, they have given their lives. They have given up everything they have. A lot of them have died for us."

The group also raised and repaired military headstones.

Originally, the cleanup had been scheduled for Saturday, but it had to be rescheduled for because of rainy conditions.

The Central Florida Cemetery Project holds cleanup events monthly, sometimes more often, and have worked at Page Jackson Cemetery and the Lakeview Cemetery, both in Sanford, as well as at Evergreen. The cleanup events are announced on the group’s Facebook page.

'It's hard to explain the meaning they (veterans) have for us,' Jennifer Eve says, talking about why volunteers work to improve veterans' gravesites. (Central Florida Cemetery Project)
