Can collecting has been wildly popular over here in Portland OR for as long as I can remember. Basically no cans that are set on the curb ever last long enough to get picked up by waste management. Typically it's homeless people who collect them but there's also enterprising immigrant families and seemingly people from other walks of life who do it, some who try to collect at more industrial scale by filling their cars with cans.
