This is what we've been waking up to the last few mornings. It's not fog , it's smoke! This is from the Big Sur fire(s) and beyond. A good accounting is to read this woman's blog a friend of mine passed onto me. (not a site for children). Also an update from KUSP.
I'm getting mild headaches and sinus problems. We try to keep the windows and doors closed but it's hard when it's summer and you have no AC! So at night we open things up, fall asleep, and wake up to the smell of smoke.
