and differnet blends for different pollution levels

You think so, try paying my real estate taxes and hurricane insurance.
That's another interesting thing.  Generally speaking, moderate income
people can not afford to move.  Property values have risen so much faster
than the taxes on them, which are based on original value plus a severely
limited annual increase, that they can't afford to move out of their present
home into one significantly smaller and less valuable because the property
taxes will increase so much that the smaller home will be more expensive to
live in than the larger one was.  Property insurance, both because of the
inflated housing values and increases by the insurance companies, has gotten
so high that people that have lived in their homes for more than 30 years,
are having to sell them because they can no longer afford the insurance.
It's so bad that the state just passed special legislation to control the
cost.  We'll see how it turns out.

The end result of all of this is that a state that only a few years ago had
one of the fastest growing populations in the country, actually has more
people leaving than they have arriving.  What's worse, at least from my
perspective, is who is leaving and who is staying.  The demographics of
Florida are changing even faster than the population levels.
