Before I got home last night, Eric took a walk - and smelled goats in the Grand water court.
He investigated further, and discovered that the hill by Angels' Flight is currently populated by a herd of brush-clearing goats. They're keeping them there 'round the clock, behind chain-link fences warning (skull-and-crossbones-style) of the goats' poisonous coats. Last I checked, this was not a logical deterrent to the homeless population...but whatevs.
He took me to see them last night. We scrabbled down the steep sidewalk to view them, eventually landing at the top of the far-side entrance to the metro line.
When we arrived, great herds of animals were gathered there - a hill full of sleeping goats on one side and a sidewalk full of stirring rats on the other, watching their new neighbors curiously and yakking quietly about them amongst themselves. It was a transfixing sight.
