This event is part of the "One Town One Book," the third annual town wide reading project sponsored by the three libraries located in Warwick Township n Albert Wisner Public Library, Florida Public Library and Greenwood Lake Public Library. The book this year is A Walk in the Woods: Rediscovering America on the Appalachian Trail by Bill Bryson. Published 1998 this is a personal memoir of the author's "thru-hike" of the Appalachian Trail and a delightful, often laugh out loud chronicle of the experiences and people he meets along the trail. This book was chosen in part because the Appalachian Trail crosses through Warwick Township and there is great enthusiasm for the outdoors in the community.
