It may have been coincidence that the racket stopped shortly after Brenna and I found the offenders, looked a moment at their generator and then took their picture. But I like to think it was the power of passive aggression.
Unfortunately, we found no kind of aggression sufficient to ward off the mosquitoes. They were brutal. That camping-in-the-open-air idea took a turn for the worse. I expected the mosquitoes to quit when it got dark and cooled off but they buzzed around my face all night until daybreak when they redoubled their efforts and numbers.
