That's quite a story...... When I look back on my own "I'm indestructible and I'm gonna live forever" stage of my human life cycle, I'm astounded that I managed to survive it alive. It just amazes me.
And I worked with a bunch of those "high school chicken picker crews". The good ones were really good - the not so good ones were.....well....not so good. But they could make pretty good money if they were willing to work at it. And it was work.
We only had one old truck that still carried those old wooden coops. Loading it was a job! Luckily we rarely used it. The rest of the trucks had the coops built right on the truck and we loaded 'em from the side while standing on a platform we carried with us that mounted on the side of the truck. And, to be honest, they weren't "18 wheelers", they were just light duty 20 tonners (tandem axle drive) with an extended wheel base - which meant it took around a quarter acre to turn 'em around. Farmers just love to take light duty trucks and use 'em for heavy duty applications. In three years, I blew up two motors (gas) in one truck and one motor in another. And loaded, I would rarely get above 45mph - and it took 5 miles to get it up to that speed.
One of really good and really bad things about driving a chicken truck was that, once loaded, nothing could stop you. With that many live chickens - failure to get back to the "processing" plant was NOT an option. One time, during the rainy, high water season, I drove across an "out in the countryside" bridge that had unknown thousands of tons of logs, debris, etc. pushed up against it on the upstream side - and I was weighing north of 40,000 pounds. No other choice at 2 in the morning. Sometimes, it was a stimulating job.......
And I too, have sometimes wondered if Oz ever sleeps - glad you asked him that.
