My guess would be that it would be very difficult to maneuver around the mountainous areas when considering the darkness and the smoke, unless they can drop from higher altitudes. I really don't know.
My wife and I worked with ARES, RACES, Animal Rescue Reserve and Project Wildlife for almost 20 years while we lived in San Diego. It's difficult to be watching this occur and be on the sidelines. Especially since my sister and her family are evacuated from their home in the Cottonwood development and wondering what's next.
