is a croger sack like a croker sack?
--which i read somewhere was a crocus sack (but why one would have sacks of crocus(vs tulips or other bulbs) was never explained.

what sort of sack do you think off? a burlap bag?

(that what i think of when i refer to a sack of potatoes, but in reality, even 50lb bags of potatoes are sold in nylon (and tyvec) bags theses day (same with 20lb bags of onions)

and smaller portions (5lb bags) are plastic! but i still say "pick up sack of potatoes, (but would never call a plastic bag a sack!)
