My heart goes out to all of you living through a wildfire. I well know the anguish and uncertainty and feelings of helplessness when a big fire roars through.

2 years ago my son and his young family barely escaped the Camp Fire that destroyed Paradise, Ca. His brand new home, just outside city limits on 40 acres was built off-grid and they'd just moved in. His new home survived the walls of flame and I'll give my take on how to improve your chances.
