Hillcrest School finished planting six new trees today that were donated to its arboretum this year. The latest donation brings a total of 51 trees planted for the arboretum on the school's property. The planting projects give students hands-on experience and an opportunity to be outside and enjoy the weather. In addition to the arboretum, the school's property also is home to a disc golf course that wraps through the field of trees.
