Eh, we rarely use them all, unless there's a major clean out. And even then, most of the time we load up trucks and minivans and haul things to the various dumps/recycling centers we have access to.
Actually, there's been quite a few times I have hauled every container at the Grove out to the street on trash days, and it has nothing to do with any major clean out. It probably doesn't get noticed because it builds gradually on a weekend. People produce a lot more trash than they realize they do. And if you are at the Grove on a weekend, do you really notice whether a can that was empty on Saturday is now full Sunday afternoon?
Soda cans , empty food bags, coffee cups, pizza boxes, refuse from cars (yes, this happens), both individual and group refuse from a ritual, gardening clippings, branches, weeds, trash bags from the Grove, trash bags from the apartments, and next thing you know, I'm hauling 4+ cans to the street, after having to bag all the loose trash that was casually dropped in as people walked by.
Which is exactly why these changes are going into effect.
