July's Theme Day at City Daily Photo is "No...." signs. This sign is at what's commonly called Boise's "Poop Farm," although the sign points out more elegantly that it's the Boise City Sewer Treatment Facility Biosolids Recycling Site. It's 4,000 acres south of town where sewage sludge is spread on crops as fertilizer. No people food crops are grown, just forage and other animal feed. An update: I found another reason to stay far, far away from this "farm," read about it here.
