Earth Day in the 1950's was any day you communed with nature, planted a tree, picked a rose, weeded the flower bed, composted your garbage, or used your trusy machete to cut down a yucca bloom. The girls in camp were impressed, but the local ranger tied us to the back of his pickup and dragged us around for awhile. Lesson learned.
Oh, that's brother Marty on my right and cousin Larry on my left. I forgot who wore the machete belt after this incident --- certainly not any of us.
