Son In Law was a Ground Fault Locator Supervisor out of Phoenix. They think he got Valley Fever early last year.
He was out in the open most of the time. Was in a lot of dust.
Caused him to develop symptoms similar to Narcoelpsy, headaches and hs right eye dilate, like a stroke.
I had no idea how serious Valley Fever was until then.
When we were out near Tucson we bought developed coughs and so forth.
The dust is often so fine you can see it but it's everywhere, even in winter or maybe especially in winter.
