I don't have a problem with bagging it and leaving it so much as not bagging it at all. The crews do clean the place up. And the dumpsters were over flowing. I'd imagine it's a lot easier to drive by on a cart and pick up a bag of trash than it is to have to stop, get out and rake trash up and put it in a bag. Like I said, sounds like an inbred children of Uranus (aka Titan) thing to do to throw garbage all over your lawn.
I'm usually one of the last ones to leave so I see the place empty after everyone has left. And never have I seen it as trashed as it was this past Sunday.
