Today, Friday, October 31, is Senior Power Day at the St. Clair County Council On Aging. Free health screenings, testing, advice and information will be available throughout the day at the agency at 600 Grand River Avenue in Port Huron. Because today is Halloween, Mary Taylor of the Council, says seniors are encouraged to come dressed in their best Halloween Costume. Over nineteen screenings will be available for attendees and sponsors will have tables set up for information. A brunch will be available and there will be door prizes to be won. Council On Aging vans are available for transportation. The event runs today from 10 a.m. to 2 p.m.
