Circuit or section hiking/backpacking can be very rewarding. You usually do not have any time restraint and aren't forced to cover large amountd of milage. It is exiting to be able to take some of the side trails. I recently hiked a few circuit hikes just off the Skyline and Blue Ridge Drives in Virginia. I observed an abandoned copper mine, a male turkey courting his mate, a bird house in a tree in the middle of nowhere, white tail deer and a monuement to Audie Murphy.
