Take advantage of the long days and warm evenings by visiting the Morris Arboretum’s Garden Railway. Opening on June 17, the railway is a miniature world set in a beautiful summer garden, with historic buildings, train tunnels and overhead trestles made entirely of natural materials. Train enthusiasts can bring their kids (and a picnic dinner) to the Arboretum on June 21, from 5:30 to 7:30 p.m., for a celebration of the new railway, “Fairy Tale Rail II.” Kids are encouraged to dress up. If trains aren’t your bag, the Arboretum also offers plenty of outdoor concerts—from international folk music on June 29 to classical guitarist Allen Krantz on July 21—and puppet shows and music for the kids. On May 13 and 14, you can ask the experts about native greenery at the annual plant sale.
