I never wrote a letter to the owners of those horses but I guess I made a big enough stink about it with the local police department that they contacted the owners. Last night I noticed that they had been moved into different stalls and today there was a guy there who was taking wheelbarrows of manure out of the stalls into the manure pile. He didn't speak English very well but he asked me if I had seen the horses at the end and I said yes. And he said, "the cops come everyday because they are skinny."
I'm so happy somethings being done. I hope it lasts. They still desperately need their hooves trimmed though.
