Book excerpt: A symbol of Indiana's past, the covered bridge still evokes feelings of nostalgia, romance, and even mystery. During the 19th century, over 500 of these handsome structures spanned the streams, rivers, and ravines of Indiana. Plagued by floods, fire, storms, neglect, and arson, today fewer than 100 remain. Marsha Williamson Mohr's photographs capture the timeless and simple beauty of these well-traveled structures from around the state, including Parke County—the unofficial covered bridge capital of the world. With 105 color photographs, Indiana's Covered Bridges will appeal to everyone who treasures Indiana's rich architectural heritage.
