On U.S. 19 in Spring Hill, Florida, a giant concrete dinosaur looms over the roadside. The former Sinclair Service Station was built in 1964, when Sinclair’s dinosaur logo was already a familiar green mascot for American motorists. Here, the branding escaped the sign and became the building itself. The creature is usually described as an Apatosaurus or Brontosaurus-like dinosaur, and it is hard to miss: 110 feet long, 30 feet wide, and 47 feet high, with a repair facility tucked inside its body.
