Retired couple Andy and Dinata Misovec are part of the backbone of National Parks -- the volunteer corp. The Misovecs help practically every year at the Great Smokey Mountains National Park. As campground hosts, what they find is sometimes shocking, oftentimes hilarious, yet they always manage to come away still feeling the wonder of nature that any American National Park will instill in any visitor who cares to look. Part journal, part thoughtful essays, Big Creek: a Closer Look at a National Park will show you why those traffic jams sometimes happen. But through broken bones, bee stings, snakes, and loose dogs, you will come away with a greater appreciation of what the National Parks mean to us as a nation.
