Yes. I spent about 30 of those years accounting for the crude oil supply for our two U.S. refineries - pipelines, exchanges, foreign crude oil ships, also some oil lease accounting, and also about 4 years or so accounting for one of the refineries and its activities, as well as a little bit of ethanol plant supply, during our brief foray into that world. The last 4 years were just kind of a hodgepodge of different accounting stuff until I was put out to pasture in late January 2017, when the company had a reduction in office staff.
