WILLINGBORO — Halie Henry joined about seven of her classmates in taking their first trip down the slide of their brand new playground last Wednesday morning. "It's actually really fun," she said with a smile. "It's better than the older one." It was the first time the students of Hawthorne Park Elementary School had the opportunity to try out the new playground they won in the 2016 TerraCycle Recyced Playground Challenge. The idea to participate in a recycling challenge came in late 2011, thanks to grandparent volunteer Lu-Ann Doyle.
