Tim Penning, professor of advertising and public relations at Grand Valley State University, has published a book composed of columns he has written for the Grand Haven Tribune over the years. He said that his columns have a wide variety of both light-hearted and serious topics, depending what was on his mind. Penning picked columns to be included in the book on the basis of what he thought would have the broadest appeal. The book is available from Amazon and Schuler Books, in stores and online, and Penning also hopes to have copies available in Grand Haven bookstores.
