On a drizzling Sept. 12, Bill and Sharon Van Horn completed their eight-year section hike journey of the Appalachian Trail (AT). Their last section of about 220 miles started in Rangeley, Me., and ended at the northern terminus at Mount Katahdin in Baxter State Park. It included 100 miles in the Maine wilderness (no towns, no place to resupply). Some hikers elect to complete the 2,189.5 mile AT in one calendar year and are known as thru-hikers. Others hike the trail in sections over any number of years, as long as it takes.
