There is nothing like taking a good summer day hike. Just recently I hiked about 8 miles on the AT from Petites Gap to Apple Orchard Falls in Virginia. The trick of a good day hike is to start early and end early before temperatures rise and take and drink lots of water.
I try to take a camera to document my progress along the trail. If something happens to me and if someone finds my camera they can tell approximately where I stopped hiking.
Look around you as you hike and observe the flowering plants:
Thin leaved sunflower
Wedged Rock Bridge
Highest point on the trail
Spider web coated with moisture from clouds
