Griswold's Old School House in Claremont is said to be haunted by the ghost of a basketball-loving teenager, heard as a ball dribbling near a cement staircase. Other reported phenomena include disembodied children's voices, self-opening doors, human-shaped mists, and inexplicable cold spots within the shopping center that now occupies the former school building. The most prominent story describes a young ghost who loved basketball, with his presence indicated by the sound of a ball dribbling near a cement staircase, according to local lore featured in LA ghost stories. Unexplained children's voices are sometimes heard when no children are present. A mist in the shape of a human has been seen moving along the interior corridor of the shops. Doors in the shopping center have been known to open by themselves. Visitors and staff have reported experiencing cold spots that appear and disappear without any obvious reason. The Old School House was once the original Claremont High School, built in 1911. After the school closed in 1963, the building was known as Griswold's Smorgasbord, a popular restaurant and bakery.
