Was thumbing though National Geographic’s new swimsuit issue at the grocery store tonight — which is very well done, would like to read it more carefully sometime — and came across a picture that blew my mind. A beach in the 1930s with a sandfly problem. To keep the sunbathers from going elsewhere, they decide to spray. The picture is of an old jalopy of a truck driving along the beach spewing immense clouds of white vapor behind it. A painted sign on the side of the truck says in giant letters:
Harmless to humans!
Reminds me that when my dad had acne as a teenager in the late 40s, the doctors were blasting his face with radiation weekly, thinking it would vanish his zits. Now he has to be checked yearly for melanoma.
