especially for this fire, jumping doesnt mean that everything 2 miles down wind also burned down. buildings that far had the opportunity to burn, and if they dud, had the opportunity to burn their neighbors, and another 2 miles down.

If the city wants buy RE for access, that is between tax payers and the land owners. Cash talks
