"How does the tree move its branches like that?" He asked. Without rising from my chair, nor looking up from my book, I started to answer, "The tree is not moving the branches, son. The wind is..." But before the words were out, I _ myself. Instead I rose from my chair and moved to the window to join my son. I looked at the tree. From inside our room, from behind the window, I could neither feel nor hear the wind. I saw instead a tree with its branches silently moving and thought to myself, from inside this room, how could I possibly be sure that the branches were moving because of the wind rather than from the tree's own willing? As I stood there with my son watching the tree, I became struck by the movement of the branches, the shimmer of the leaves. My mind quieted and I became less sure myself of what was causing the branches to move. Was it the wind, or was it some expressive, independent movement of the tree? "I see what you mean," I said to my son. "The movement of the tree is very beautiful." "Do you think the tree is dancing?" asked my son. "Why would it be dancing?" I asked. "Maybe it is happy because the sun is shining," he said. "Perhaps," I said. "Or because it's spring," he added, "and it's not cold any more." "Perhaps," I said. As we continued to watch the tree together, I, too, began to appreciate the dance of the tree. I enjoyed the movement and sway of the branches, seeing little nuances that I hadn't noticed before.

Why do you ask?" "Because this tree looks happy," he answered. "Can a tree be happy or sad?" "What do you mean?" I asked. "In the winter, trees seem sad," he said. "Their branches hang down, and they look cold and lonely. But now with the leaves on the tree and the sun shining and the...

At about 2,189 miles, the Appalachian Trail is the longest single unit of the National Park System. With the number of people visiting this place increasing each year, the chances are great that any of us may damage the natural environment along the Trail and affect the experience for others. So please do your part by following these hiking and camping practices, and encourage others to learn about and adopt these techniques. 1 Plan ahead and prepare. Evaluate the risks associated with your outing, identify campsites and destinations in advance, and use maps and guides. Prepare for extreme weather, dangers, and emergencies - especially the cold - to avoid impacts from searches, rescues, and campfires. Learn when areas are most crowded and try to avoid those times. 2 Dispose of waste properly. Pack out all trash and food waste, including that left behind by others. Don't bury trash or food, and don't try to burn packaging materials in campfires. Use the privy for human waste only. Do not add trash. If there is no privy, dispose of human waste by burying it in a hole, a hole at least 200 feet (80 steps) from campsites, water sources and shelters, and well away from trails. 3 Leave what you find. Leave plants, cultural artifacts and other natural objects where you found them for others to enjoy. Do not damage live trees or plants; green wood burns poorly. Collect only firewood that is dead, down, and no larger than your wrist. Leave dead standing trees and dead limbs on standing trees for the wildlife. 4 Minimize campfire impacts. Use stoves for cooking - if you need a fire, build one only where it's legal and in an existing fire ring. Keep fires small. Never leave your campfire unattended, and drown it when you leave. Do not try to burn trash, including plastic, glass, cans, tea bags, food, or anything with food on it. These items do not burn thoroughly. They create harmful fumes , and attract wildlife like... Question: Before you hike on the Appalachian Trail, you are advised to _ . - keep everything that you find there - bring some food for the wildlife there - prepare for bad weather and emergencies - avoid crowded periods and book a hotel in advance
