An undefeated Bulloch County squad is “playing” Saturday at South Effingham High School as the top-seeded team with a state title on the line. The 80-strong squad is The Swarm — Southeast Bulloch High’s amazing marching band — and they will compete on Mustang Field in Guyton in the finals of the 2013 Georgia Marching Band Series. Twelve teams qualified for the state finals, which gets underway with Banks County performing at 1:20 p.m. And as the band that earned the highest marks during the season, The Swarm will take the field last — at 7:20 p.m. Saturday.
