The animal group PETA is calling on Thunder Bay Mayor Lynn Peterson to ban horse drawn carriages in the city. PETA's request follows a May 31st incident in which 4 year old Willow Scott-Hannam was killed. PETA says similar incidents have happened in other city's as well. Director Debbie Leahy says forcing horses to pull heavy loads is cruel and is an accident waiting to happen. Mayor Lynn Peterson has yet to comment.
