Keith, the only air-conditioning we had back then was the fan-action generated by the wings of flies in our classroom. We didn't have any livestock nearby, so the A/C was intermittent at best...lol
I was never able to say I walked 3 miles to school in the snow--uphill both ways--because we lived a little closer and it was usually warm. But I can say that I carried a Bowie knife to cut windows in the smog in front of me as I walked to school :)
