WOW..
My hometown feed store, (not a co-op, or chain store, a mom and pop operation), doesn't carry AM in stock, but if I get my order in by Friday, it's there the following Wednesday like clockwork.
When I asked them, they said Purina delivers every Wed, if you want one bag or 10 we can get it for you.

I had them do some checking, and all varieties of AM were in stock at whatever warehouse they use.

Interestingly enough, they said they order more AM 2000 than anything else. I figured most folks must be feeding catfish?

"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.
