Hal Hubbs, Charles Maynard, and David Morris have hiked together and with their families for many years. The three friends formed Panther Press, which originally published Waterfalls and Cascades of the Great Smoky Mountains, along with many other titles on natural history, particularly in the Smokies. Hal, Charles, and David have worked as volunteers in the Smokies and have hiked in many national parks throughout the country. But as long time East Tennessee residents, they especially want families to enjoy the trails of Great Smoky Mountains National Park.
