The revival of prime time TV soap opera “Dallas” brings to mind a local oilman, the late Danny Biggs.He was nothing like the fictional oilman J.R. Ewing, played by Larry Hagman from 1979-1991, and back for the 2012 sequel. J.R. was a larger than life TV villain we loved to hate; the Ewings were rich Texans who made their fortune in cattle and oil with shady backstabbing deals. “It’s nothing like ‘Dallas!’” Biggs used to say of the oil business.
