As an Oregonian, I hate this system. It's old, archaic and now pointless. The idea behind it was to increase recycling of cans and bottles, and it did it's job. In the 70s and 80s, it was great to push that for the social good. But it's done it's job, two generations are now recycling more than ever and the coverage for curbside recycling is very high in Oregon. But the redemption rate has plummeted in the last decad…
Bottles and cans with deposit that are thrown into curb-side mixed-waste bins (or just on the ground) are usually very quickly collected by people looking for extra cash (on summer weekends this can net you quite a lot!) In some places I've seen small separate can receptables attached to garbage bins that can hold a stack of cans so that it's easy for someone to come grab them without having to delve into the garbage bin proper, which I find a very good idea.
