The Carlisle Area School District says it can save up to $15,000 a year by turning over some landscaping chores to sheep.
The Patriot-News of Harrisburg reports the district is using the sheep to keep the grass near its solar panels neatly trimmed. The sheep nibble grass in the morning and take refuge in the shade of the panels in the afternoon.
With the food already on hand, the district need only supply the sheep with water.
A middle school assistant principal is providing the sheep. Eric Sands says he's still trying to figure out exactly how many sheep he needs to use to keep the area clear.
