The funny part of basic arithmetic
 

As lead has been (hysterically) removed from everything ELSE,
the same total amount of lead in AVGAS
suddenly becomes statistically larger
as a part of what is left to worry about becomes smaller.

In Maryland, I ordered some brass fixtures for the restrooms.
Stylish, eh?

Two online orders got cancelled.
I wondered, "What gives?"

The State of MD had issued a law making it illegal to sell brass in the state
UNLESS it had been certified manufactured in a lead free process.

And the initial idea of waiting for FAA to pick winners and losers is, itself, a losing proposition.

Ultimately, the private sector will decide whether or not to be bound to just how much of certification requirements.
