One intermittent and looked forward to summer evening event, when I was a kid, was the Mosquito Fogger. A city truck, carrying a large tank of insecticide and the fogging device, would slowly cruise the residential streets. The Fogger, powered by a small gasoline engine which announced its presence a couple of blocks away, would generate clouds of what we all thought of as smoke.
Gravitating to the sound of the engine, flocks of children would walk along behind the fogger, inside the dense cloud of “smoke”, breathing deep of the strange smelling vapor. We all thought this was great fun. The guys in the truck ignored us, and our parents didn’t seem bothered by it all. But, despite what seems obvious today, we all seem to have survived.
Actually, I think the mosquitoes mostly survived the experience, as well.
