I lived in the Bay Area for a while and didn't know. It would also be cool if for entering the address it did autocomplete with valid addresses.
so if you are in the zone some prep helps, keeping phone charged, car keys handy ...
autocomplete sounds fun, i'll try
feels silly that I did not realize that fires do not have zone boundaries, and warnings to adjacent areas are a deliberate choice. no one knows which way the wind blows. so glad it got called by the fire expert
