NORTH LIBERTY– Goats on the Go did their job during their stay at Penn Elementary Saturday, May 14, through Tuesday, May 17. The school grounds crew also cut out all of the smaller woody vegetation and applied a type of grass seed that will grow quickly and help keep back weeds. This type of grass will only survive one year. In the next few weeks, a tree company will visit Penn to remove large “junk” tress– primarily ash trees. Throughout the summer, the grounds crew will continue to work on small projects, such as leveling low spots, removing stumps and cleaning the fence.
