Way out west, where fossils are found, brontosaur signs appear all 'round -- and they belong to The Sinclair Companies' Sinclair Oil. The iconic brontosaur logo appears at more than 2,700 Sinclair-branded gas stations owned by independent operators in 22 US states. The company also operates two oil refineries, more than 1,000 miles of pipelines, exploration operations, and a trucking fleet. It owns a 60,000-barrels-per-day refinery in Sinclair, near Rawlins, Wyoming, and a 20,000-barrels-per-day unit in Casper, Wyoming. Sinclair Companies also owns the Grand America Hotel, the Little America hotel chain, and two ski resorts (Sun Valley in Idaho and Snowbasin in Utah).
