I gotta ask....how fast are you guys driving on those stone drives to make all that dust?? grin

Crushed limestone is used on most of our county roads here, and yes sir it's dusty! But, there's a lot more traffic on a county road, crushing those rocks into dust, than there is on a driveway. And, the posted speed limit is 30-35 mph....I don't need to drive that fast on my driveway?

"Forget pounds and ounces, I'm figuring displacement!"

If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT?
PB answer: It depends.
