Politics at its most local.

Just south of Glen Rock, Pa., stands the community’s original, one-room schoolhouse, built in 1896. Across the street from the red-brick building, cows lounge about a farm, and cherry trees are flowering around a small pond. Towering on a hill above it is the modern campus of Southern York County School District, which boasts almost 3,000 students, three buildings, and sprawling athletic fields.
