Because I am an inquisitive person (especially on recycling night) I stopped to look at this on my way home last night, in front of a house on my street.

Hmmm.

Very large paper bags.
On the way back from my run later I grabbed the whole bale, lugged it home, and plunked it on the table.

Holy moly, what is that design?
Weird!
And, yes, they are big (I have normal-size feet):

The world is a very interesting place.
