I worked on the slime line gutting salmon in Alaska during one summer. It was a cold, wet, smelly (though you eventually kind of got used to it but maybe because you always smelled like fish) kind of job. They had a mobile home people would go to for the breaks. Out of about 75 people at work, I was the solitary individual who didn't smoke. You literally couldn't see to the end of the trailer through all the cigarette smoke. So I'd just sit outside in the rain by myself during the breaks. I guess what I really didn't like was that that was the only place I ever worked where I had nothing in common with anybody I met there. You'd be pulling guts out of fish on the line as fast as you could because they came down the line really fast and you'd swear an hour had gone by and you look up at the clock and it was only fifteen minutes. From what I'm hearing it was a better job than working at 39N!
Best non-flying job? Tie between vibration analysis work on ships (ride the ship for a few days, great pay) and lifeguard (poor pay, great-looking co-workers and customers, easy).
