Recently Hillside mailed a letter to our heating oil customers. There was a hidden gem on the back of that letter. For those that may have missed the gem, it was instructions on how to make a paper airplane, Hillside’s way of not completely wasting paper. One of our long-standing automatic delivery customers, Jeff R, found this hidden gem and sent us a picture of his creation. Thanks Jeff!
