BTW- I am not against shelter in place. It worked well for those in the Barona casino during the height of the Cedar fire. However, it did not work well for everyone:

“CEDAR FIRE, San Diego County: 14 people dead, 2232 homes, 22 commercial properties and 566 outbuildings destroyed, 280293 acres burned.
SAN DIEGO, California (CNN) — Firefighters on Friday controlled fourteen of nearly two dozen Southern California wildfires, which authorities have directly blamed for seven deaths.”

It really depends on the intensity of the fire and how safe the place you are using for shelter is.
