Some years ago I was driving down Hoddle Street in heavy traffic when the back seat erupted (kids) I was fearing the worst when I spied above me a huntsman... big it was... it moved quickly ending its journey behind the sun visor. There was nowhere to stop! I showed no fear - not even when it reverse out, only to scuttle back when the noise reached a new crescendo... Sorry the only turrets I know-of are in captivity.
