Entrance to the Erie Art Museum in Erie, Pennsylvania, the state’s fourth-largest city that does, indeed, lie on the banks of Lake Erie — one of the United States’ five “Great Lakes.” Huddled outside is artist John Silk Deckard’s 1978 “Eternal Vigilance” sculpture, which the museum calls “a moment of tortured humanity captured in 500 pounds of bronze.” Photo by Carol Highsmith, 2019.
