Like many other retired Americans we like to travel in our beautiful country, but instead of traveling in a motor home we carry all our gear in backpacks. Since 1998 we have logged nearly 16,000 miles of hiking through 31 states. These miles include 4 major long trails - the Pacific Crest Trail, Continental Divide Trail, Appalachian Trail and American Discovery Trail. These four trails have been called The Grand Slam of Long Distance Hiking.
