Check out Detroit's. This particular one had the added benefit of a broken water main that went unfixed for months, and might continue to this day. Sort of an impromptu water sprinkler system.
By the way, I attended the CRA neighborhood meeting last night at the Shuffleboard Court building. The meeting's focus was on the western neighborhoods of the between 7th Avenue North and 7th Avenue South. I'll have more later on the meeting in the form of video and some still shots. Fairly well attended, as these meetings go.
