Big stars lit up the night during last week’s 28th annual Dinner Under the Stars. We were honored to have Agriculture Secretary Tom Vilsack, Senator Debbie Stabenow (D-MI), and Representative Glenn “GT” Thompson (R-PA) as our esteemed speakers. As guests sat amidst the National Arboretum’s living museum of trees, Secretary Vilsack marveled at how trees communicate and support each other across species through an underground fungal network where they share resources like nutrients and water.
