What are they doing with these aluminum cans?
As you can see in the photo, they store their cans, in bags, in the back. The people that came to get the cans are putting them into bigger bags and packing them into a huge box truck very tightly as if they are going to fill with as many as they can. Not like it is just going across town.
If these cans are to go to another state for a higher redemption price, don't machines read the bar codes to prevent that?
Also, the truck had a license plate from Sonora, Mexico. Although that is pretty common around here, that may be part of the reason.
