I am in Monterey County where three fires are burning - River Fire (Salinas, 49000 acres), Carmel Fire (Carmel Valley, 7000 acres), and Dolan Fire (Big Sur, 22000 acres) - and can see the bright orange glow of flames from my backyard when smoke permits, and from the safety of town < 4 miles as the crow flies to the nearest perimeter. I wish I'd bought more than one $20 Oregon Scientific HEPA air purifier from Woot last December.
