FOR HALLOWEEN we offer two ghost stories for the price of one."The Shadow of White Death" – City Park Police in New Orleans do not have a dangerous beat, except for the occasional apparition, nebulous images of people who met untimely deaths in the large, urban park. Is the young woman with long black hair and wearing a white gown real or an unearthly spirit?"Vermilion Bay" – In Acadiana, Cajuns learn how to fish as naturally as learning how to walk. Catching catfish is expected, a World War I bi-plane flown by a pretty green-eyed woman with reddish-brown hair landing next to Vermilion Bay is not.
