Is Lawrence High the only Sunflower League school that doesn't have a Free State Firebird logo in its main gym?
No. Like Lawrence High, Shawnee Mission Northwest displays logos of every Sunflower League school except for Free State. Free State, Shawnee Mission West and Leavenworth don't display any logos of their fellow league schools. Olathe South, Olathe East, Olathe North, SM North, SM East and SM South display logos from all league schools.
