In about 1960 armadillos staged a mass invasion of northeast Texas. I was just a kid, but I had never seen an armadillo and I remember the adults reaction to their takeover. They got to be a nuisance and we tried to kill as many as we could. By '65 or so I was old enough to take off after them. Hunted at night. My best friend and I somehow learned about carbide lights and bought ourselves carbide lights at the army surplus store. If you've never seen one they were made of brass with a large polished metal reflector about 4 inches in diameter. There were two vessels, one for water on top and one below, sealed and gasketed to hold pressure. Water from the top tank dripped down onto the "rocks" below. The rocks were calcium carbide (hence the name of the light). Water caused the carbide to release acetylene gas which went out through a tiny nozzle and you lit it by means of a striker like on Zippo lighters. Made a good bright light and were cheaper to operate than a battery powered flashlight. This was WAY before LED flashlights! Lots of good memories, hunting with my friend and my dog. As I recall, he had more fun even than we did. A few years went by and girlfriends replaced the Saturday night hunts. We double dated occasionally and he was best man in our wedding and I in his.
