Name one thing...
On a Labor Day weekend around 1997....I stood on top of the roof at the Armour hot-dog works in Martin City, KS in the middle of a raging lightning/thunderstorm welding a "tie-in" ammonia header pipe to the main trunk line from the compressor room while a local "part-timer" held an umbrella over my head. Lightning bolts were coming down all over the place!!!
If those welds didn't get made.......500 people would not be able to go to work on Monday morning.
