Spraying for mosquitos used to be quite common in and around Dallas. In a nearby town where I lived during grade school, they regularly had mosquito spraying trucks go up and down the street putting out huge clouds of pesticide.
We called them "the fogging machines" and whenever they came up the street I and a group of friends would jump on our bikes and follow as close behind the trucks as possible so we could be completely enveloped in the fog.
Yep, there we were peddling furiously and breathing in and out heavily and sucking in the fumes only a couple of feet away from the fog nozzle for blocks at a time. Great fun. And hey, it was only DDT . . .
