there is someone in my neighborhood who must have an eating disorder or something. On occasion, while i'm out running, i'll come across a pile of puke in the middle of sidewalk. Right now its just every once and a while...but last summer all the way through to the holidays there was a new pile of puke every day. In the summer, it stank and then crusted onto the sidewalk..in the winter it iced over and i slipped on it once. Totally gross!!!
