Mosquito Spraying

In the late 50's and early 60's the city would spray for mosquitoes in the summer. A "fogger" truck would go up and down each street in the early evening spewing out a giant cloud of fog behind it. The neighborhood kids would often ride our bikes in and out of the fog with it stinging our eyes and making us choke. Sometimes I wonder if it was DDT they were spraying and what that might have done to us!
