Yeah at the other park I find a lot of pet baggies, so to speak. Its like if you are going to go thru the work involved in putting the stuff into a plastic bag, then why in the world do they feel the need to check said bag into the brush. I think it is better off at that point to forget the bag, check the stuff into said brush and let nature do its thing. If they are going to bag it, take the stuff on the way out lol.
