I thought Sinclears got bought by one of the major a long time ago. Went to Wikipedia and they did. Arco bought them in 1969. Spun them off in 1976 and a Private investor bought them They still have 2 refineries in Wyoming and 1500 Service Stations. Have not seen a Sinclear Station with the Dinosaur for a long time. They are based in Salt Lake City. Though some of the oil guys on here might know of their existence.
