Students of Southeast Bulloch High School will gather Saturday to keep with tradition and experience the final highlight of their high school careers; they will graduate, too. For a 20th consecutive year, parent volunteers will host a post-graduation, overnight event for the Brooklet school’s graduating seniors. Project Graduation, a nationwide initiative providing students a drug and alcohol-free celebration on the night of commencement, will kick-off at 11 p.m. Saturday at The Clubhouse at Hackers.
