We were working 24 on, maybe 20 off at the time. Months on end. It was rare that I had anytime to myself, at work. Nights is where you really learned to do what you had to do, to keep 5-7 worn out POS gen sets running, and not letting the system go down. So when we had a little time to ourselves, I read a book, or took something apart. One for the brain, one for work. This is one of my happier times in my life.
