DOUBLE TAP TO ZOOM WITH PHONE OR TABLET To my mother, Kathy Starbuck, who gave me snakes, saved painted turtles, and never met a wasp she couldn’t catch. Your delight in the wonders of nature was an invitation to a young child and continues to inspire me. Thank you for this gift. —Sara D To my daughters, Haleigh, Taylor, and Avery, who love to learn as much as I love to teach. To all my past students and parents from the Child Development Lab at Southern Illinois University Carbondale—now that I have kids of my own, I realize that you taught me more than I ever taught you. —Marla D To my students, past and present, who have chosen a career in connecting people with plants through landscape horticulture and forestry. We are all big kids in gardens. —Karen COPYRIGHTED MATERIAL Running Foot  •  v
