The Rougarou - Southern Louisiana
By DS Duby http://dsduby.hubpages.com/
The legends of the rougarou, or loup-garou, have been passed down from generation to generation as long as Louisiana has been inhabited by modern man. The rougarou are closely related to the European version of the werewolf, but has a few very distinct differences from the wolf men seen in movies and on television.
Wolves are not native to Louisiana, so many times the beast in the story is replaced with other animals such as dogs, pigs or cattle, and generally appear as being pale white in color. As the story goes, the rougarou will wander the streets at night searching for a savior amongst the crowds of people. It will run through and cause havoc to each individual until somebody eventually shoots or stabs the creature.

Parents are often known to spin the tales of the rougarou to children who misbehave, warning them that if they don't straighten up they will be visited by the rougarou in their bed come nightfall. One account tells of a boy who encountered the beast while on his way home from a night out with friends. As the boy was walking along a large white dog was following behind nipping at his heels and antagonizing the boy to attack. Finally out of annoyance and slight anger the boy took out his knife and slashed the dog open, at that point the beast then turned back into a man.
In this case, the rougarou told the boy how he had sold his soul to the devil to gain prosperity, but was tricked by Satan and changed into the beast instead. As the curse seems to demand, he then warned the boy of the penalty of mentioning the events that had taken place, but the boy just couldn't resist.
After repeating the story to several friends the boy started to disappear from his room at night and none of his friends of family could find him anywhere until the following morning, at which point he would appear back in his room with no explanation to where he had been.
This went on for about a year, until one morning his body was found laying in the street. The police claimed it was most likely suicide, but friends and family of the boy knew that there would soon be a new rougarou roaming the streets. Anyone who has ever lived in a small town knows that no story can be kept secret for long, not even the tale of the rougarou.
The Attakapas Indians called it Atchafalaya or "long river". Stretching over 135 miles, the Atchafalaya river has been the life line affecting the history and tradition of Morgan City. From its first Attakapas residents to the present day shrimping and oil trade, the river has provided prosperity and opportunity coupled with difficult challenges to many generations. As the tide ebbs and flows along the river, so does Morgan City. The city is a "gumbo" of French, Spanish, Italian, German, Dutch, Native and African American heritages blended into a strong belief in faith, tradition and family that define the strength of the city today. 
The late 1800s and early 1900s was an era of growth and development. Many of the historic buildings such as Sacred Heart Catholic Church, Trinity Episcopal Church, and Pharr Chapel Methodist as well as distinctive homes including Cotton Top, the Norman-Schreier House, and the Turn-of-the-Century House were constructed. Boat building, moss picking, and a shell crushing plant broadened Morgan City's economic base.
