From 1970 to 85 i was a barber and then started with the Gas Utility in New Orleans. While there I started as a dispatcher then went to the Cathodic Protection dept.,[ we kept a small amount of DC current on the steel main and services to prevent corrosion], Then leak survey [patroled city with infrared to detect methane gases] and back to C|P. All these jobs were fairly easy but after Katrina everyone had to work. In New Orleans most of the gas meters are under the house and all had to be shut off to empty the water out of the gas mains and services. You can imagine after 2 weeks how rusted the shutoff valves would be.
So I retired.
Long winded, but that's what I did.
