Been a CA, resident all my life. S.F. Bay area. This is the cause of the problem.
1. Pacific Gas and Electric. Deferred maintenance of gas and electrical lines.
ie. 100 yr old, towers. Electrical cable/power lines snap, Hot wire hits tower,
metal melts, molten metal hits ground/trees, Or hot wire hits nearby trees.
Add a little wind, disaster.
P.G.E. Management put profits ahead of common sense.
Ca. Public Utilities Commission. Suppose to oversee PGE, Failed.
2. California. Has Environmental Activists/laws. Do not clear out dead trees. Do not
build fire breaks, No clear cutting. Leave "Nature" to take care of our forest.
Many "timber" companies, were put out of business. So are forest are no longer
managed. The ground under the forest is full dead trees, brush, etc.
So instead of a small ground fire, we have entire forests burn up.
Some of you "old timers", out there, if you listened to KGO, Bill Wattenburg, (check him out, just passed away), he always warned us, there is going to be a fire storm in CA,
if we do not take care of our forests. Took, about 10+ years, but now it's happening.
Sorry if I'm off topic. But if proper prevention and common sense prevailed, We Californians would not be in the mess we are having.
