It usually takes more than half a year for individuals to complete an Appalachian Trail experience. Local families will need just a weekend for the same — thanks to State College Area School District librarians. On Saturday and Sunday, the library department will hold “State to State: Hike the Appalachian Trail Across SCASD,” part of this year’s SCASD Reads (#ScasdREADS) campaign, “Read It, Walk It, SCASD Libraries on the Trail.” The campaign this spring has featured the books “Grandma Gatewood’s Walk,” an account of Emma Gatewood’s historic solo AT hike as a 67-year-old grandmother in 1955, for State High students; “The Unlikely Thru-Hiker,” Derick Lugo’s memoir about traversing the trail as a novice African-American hiker from Brooklyn, for middle school students; and “Grandma Gatewood Hikes the Appalachian Trail,” a children’s book read to elementary students on May 3, the date Gatewood began the first of her three AT hikes.
