Be sure to join others at the Museum for the last ever Ghosts of a Chance and Return of the Spirits event. Decipher codes, follow treasure maps, send text messages, and uncover hidden objects in 'Ghosts of a Chance,' the museum's original multimedia scavenger hunt, or in 'Return of the Spirits,' a sequel based on the same characters. Halloween costumes encouraged.
