Hoopingarner volunteers for the Clay County Humane Society (CCHS), which runs the concession stand during the Brazil Concert Band concerts.
"She's the county's A No. 1 volunteer," CCHS volunteer Laura DeMers said.
DeMers had run the volunteer program for eight years. CCHS has used the concession stand for 10 years for benefits. All proceeds from concession sales go to the organization.
On Sunday, the organization elected to honor Hoopingarner by renaming the concession stand.
It will now be known as, "Annie's Snack Shack."
"Ann has never missed a day," DeMers said of Hoopingarner, who sells beverages and popcorn to those in attendance while walking through the crowds.
Hoopingarner was unaware Sunday was her day.
"Thank you very much," she told the crowd as they gave her a standing ovation. "I didn't know this was going to happen."
