Earth Day Story Walk with the Bethlehem Library: For Preschoolers and Parents on Friday, April 20, at 10 am at the Swift Preserve, Delmar, NY. In honor of Earth Day 2018, we are partnering with the Bethlehem Library to offer an outdoor story walk for preschoolers and their parents. We'll take a short walk through the Swift Preserve, noticing the amazing plants and animals that surround us, before sitting down to enjoy a story in the open air.
