Trilogy of Homes Scavenger Hunts Earn Girls Scouts Silver Award Roswell Girl Scout Troop 11485 hosted three History Hunts recently to educate local Girl Scouts and area residents about Roswells historic Trilogy of Homes, The Smith Plantation, Barrington Hall and Bulloch Hall. The History Hunts tours were coordinated as the Girls Scouts Silver Award project, the highest award a Girl Scout Cadette (Girl Scouts in sixth, seventh and eighth grades) can earn. Through the project, the Girl Scouts learned how to manage projects, how to speak in public, and how to work with community leaders.
