The rooftop’s patrons are a cross-section of the city’s edges: mechanics in grease-slick boots, kids with goggles on their foreheads, a retired radio operator who insists on calling himself “Marshal.” They watch as though the machines are telling an old story in a new dialect. Conversations orbit technical minutiae—compression ratios, aftermarket injectors—but the real language is admiration and affection. A child runs a fingertip along V8’s flank; an elder taps Animo’s casing and grins, remembering the first time he learned to coax life from metal.
