Let's give a hand to the hands-on people this industry relies on.
There's a special kind of guy who comes into a classroom and heads right for the back row. Our industry is full of them. No matter how many other seats there are, he's going for the back row. If the back row's full, he'll grab a chair and drag it to the back row. I fondly call these folks “The Back Row Boys.” Whether anyone knows it, they're one smart bunch.
I first got to know the Back Row Boys when I taught college industrial technology. The next easiest thing to major in after phys ed was supposed to be industrial arts, otherwise known as shop, so there they were in the back row of my class.
