Well put, everyone. I, like many of us am getting along in years and the observation of the "new generation", with it's preoccupation with this technical society, is taking away the joy and excitement of the hands on theory...like the personal satisfaction of "messing" with a car from driving it to working on it...not that's it's just a way to get from point A to point B...agreed; it is very sad..However, if one never is exposed to this simple idea of the A/B concept...one never misses it or even knows that it exists...SAD...Carl
