Early in the 1999-2000 school year, at the request of Mamie Vest, the County Line School Board voted to designate the first in June each year as: County Line Alumni Day. In 2000, approximately 450 alumni reunited to celebrate the 50th Year Anniversary of County Line. The reunion has been held in the school cafeteria each year. The class celebrating their 50th is recognized as honored guests during the program.
Two years ago, Blane King began organizing the 70s-early 80s reunion on the first night, following the daytime event. It is a bit more up-tempo and those participating have enjoyed dinner, dancing, and visiting.
