This is the remains of a long ago experiment called rooftop cattle ranching. It was the brainchild of Robert Knotallthere's. The venture didn't work very well. The cattle kept climbing down the fire escape to frequent the local bars. Robert would get a call around 2 AM every morning to come pay the tab and fetch his cattle. One thing everyone did agree on, though, was that Robert's herd was the best rye and barley-fed meat they had ever eaten!
