The show will be preceded by a reception for alumni, who will find scrapbooks, jackets, newspaper clippings and footage of past performances on display. The reception will be from 2:30 to 3:30 p.m. in rooms 125 and 126 near the high school cafeteria.
Past members have been contacting Sanders and other event organizers, generating a buzz for the home show.
"They're anxious to see a lot of the past classmates and staff," said Sanders, who expects about 100 alumni to attend.
"You get it in your blood, and you just love doing it," said the guard's seamstress, Alice Sanders.
With enough interest, a second order might be placed for commemorative T-shirts, guard mom Camille Bowie said.
Bowie, who credits Vince Sanders with the unit's longevity, said former high school band director David Wenerd first established a unit in Waynesboro.
Twenty-five years is a notable lifetime for a color guard. The organization Winter Guard International, which is generally regarded as the activity's governing body, is entering its 30th year.
The Waynesboro squad has several parents who have been aiding the performers for more than 10 years. Bowie said people from other schools frequently comment on the number of adults who lay out Waynesboro's floor covering and set up props.
"The one thing that sets (us) apart are the alumni parents that continue to go with us," Bowie said.
The show Feb. 24, which begins at 4 p.m., is expected to draw more than 1,000 people to the school and require 50 people to run.
"I think it'll be really fun the day of the show," Vince Sanders said.
"It'll be really great to see the past members," Alice Sanders said.
