The Mainstreet Memories Car Show in Port Huron continues its tradition of supporting local causes, donating $30,000 to the Council on Aging for seniors in St. Clair County. The car show, which features classic cars, music, and family activities, partners with the COA to fund programs like meals, transportation, and social events. This year’s donation, presented on Monday, also included contributions to the Tires and Treads Community Project and the Child Abuse/Neglect Council, both of which support local children.
