This officer wrote back and said that he agreed - he said that he did know two responsible caregivers there. The problem he said was with other people littering in the area. He said he had tried to speak to some of them and were aggressive when he spoke to them.
He told them to feed away from human traffic and to clear away the plastic containers, but he said when he came back an hour later, they were still there.
I told him in that case it may be best to get NEA to step in and help. He said he had not done so yet. Unfortunately if the people littering will not listen to advice, there may be no choice.
