I’m a liberal not upraised no polo shirts not a yuppie (not young anymore) gulping wine in temecula not driving a prius, worse, riding a bicycle, concerned about the quarry. But…

how bad is this thing? should I actually be concerned?

It’s difficult to tell? Do other large population centers have quarries near them?

I value air that is breathable as I rely on the air for basic life funtions.
