Maclay, of Arendtsville, is a timber framer by trade, building barns of his own with both modern and traditional tools. On this warm autumn afternoon, however, he was surveying barns for Historic Gettysburg Adams County (HGAC), a nonprofit that seeks out barns in the county to preserve, offering both historic status to owners and grant money that could help them shore up shoddy roofs and keep the elements at bay. This year, the group will dole out $12,000 to owners to help with critical repairs. Money comes from donations and fund-raisers, like HGAC’s sixth annual “Civil War Barn Dance" on Oct. 5 at Beech Springs Farms in Orrtanna.
