Thanks to the Pokagon Band of Potawatomi, parents who sign their kids up for library cards at the Hartford Library in the next week or so will be able to get a free trip to the Potawatomi Zoo in South Bend. The trip will take place Tuesday, August 15. The promotion is all part of the Hartford Public Library Card campaign. Any children or parents who get a new library card and borrow a book can take part in that free trip. The goal is to register more than 75 new children with library cards. Anyone looking for more information can contact the Hartford Library.
