Episode Overview

In this episode, Jenny Eric welcomes playground designer and author Rusty Keeler to discuss the critical role of free play, particularly in natural and “risky” environments, in childhood development. Drawing on decades of international experience, Keeler reflects on the history, design, and cultural perceptions of play spaces, advocating for approaches that say “yes” to children’s creative impulses and autonomy. The conversation ranges from the personal to policy-level barriers and facilitators of real, messy, and meaningful play.

Key Discussion Points & Insights

1. Rusty Keeler’s Path Into Play Design

• Career Journey (03:11–10:27)
  • Rusty came into playground design from an industrial design background.
  • His early U.S. work with Kompan introduced him to play equipment focused on developmental goals.
  • His experience in the Netherlands shifted his perspective from equipment-centric to environment-centric, inspiring more natural, fluid, and unique spaces.
  • "I started remembering my own childhood...roaming and ranging in fields...and realized how important that was for my growth and development." (05:12)

2. The Evolution and Purpose of Playgrounds

• Playgrounds Then and Now (12:16–15:22)
  • Original playgrounds exemplified risk: higher, bigger, rougher. Over time, these have been sanitized due to safety and litigation concerns.
  • Rusty notes that much of traditional play equipment mimics natural elements (trees, rocks), but lacks the richness of actual nature.
  • "A lot of that equipment was just taking a tree...and I realized, maybe the natural world is already doing that." (13:10)

3. The Crisis of Lost Free Play in Childhood

• Health, Society, and the Absence of Play (15:22–17:46)
  • Both children and adult society suffer when play is removed from the public sphere; it diminishes connection, inspiration, and “aliveness.”
  • Adults' willingness to allow play is—as Rusty notes—a crucial part of the ecosystem.
  • "Whenever I see children playing in rich, deep ways, I feel happy and inspired...I’m also impressed with the adults who are allowing it." —Jenny Eric, quoting Rusty (16:44)

4. “Places That Say Yes” and the Power of Loose Parts

• Designing for Open-Ended Play (17:46–20:23)
  • Rusty previously focused on aesthetics, but came to see the liberating creativity of loose parts—even tires and boards.
  • Children need “yes” from place, materials, and adults—permission to use and reimagine spaces as they desire.
  • "Loose parts that are a little beat up...are saying to the child, use me how you want." (18:38)

5. Sudbury Valley & Self-Directed Learning

• Sudbury Valley School Experience (21:40–29:00)
  • Sudbury Valley offers multi-age, fully self-directed learning: no grades, classes, or forced participation.
  • Rusty was approached by children to create play structures in their woods—“hired by kids” and allowed to enable their vision.
  • Not all children had to participate, highlighting true freedom in learning.
  • "It’s interesting to see...some kids didn’t care at all what was going on in the woods...they could be exposed to it...but if it wasn’t floating their boat, they were involved in other things." (25:13)

6. Global Perspectives & Universal Needs

• Tours of Play Around the World (29:00–31:36)
  • Play looks different everywhere, but the drive and benefits are universal.
  • Exposure to natural, loose-part spaces occurs in Japan, Germany, New Zealand, and elsewhere.
  • "Beneath the surface, children have that drive to play, to learn and grow, right? It’s in our spirits, our DNA." (29:22)

7. Risky Play & Brain Development

• Why Kids Seek Risk (31:36–39:48)
  • Children’s risky behavior is biologically driven, helping develop the prefrontal cortex through complex decision-making.
  • Adults are often uncomfortable, but their impulse to intervene can rob kids of essential learning about self-regulation, limits, and resilience.
  • "They want to be on the edge...it bumps into adults, our comfort zone...So we jump in and say no...But what are we robbing them of?" (34:07)
  • Advice: Pause, observe, and let children self-assess risks before intervening; trust their built-in safety instincts.

8. Risk-Benefit Analysis & Navigating Licensing

• Balancing Safety and Growth (39:48–49:46)
  • Rusty’s book includes tools for negotiating with licensing—risk-benefit charts and terminology (“risk” vs. “hazard”).
  • "A risk is something children can see and choose; a hazard is something they can’t see or choose." (47:23)
  • Communication with regulators should focus on educational intention and evidence-based benefit, not blanket restriction.

9. The Importance of Mixed-Age Play

• Facilitating and Valuing Age Diversity (50:04–55:46)
  • Mixed-age play fosters leadership, empathy, and more authentic community than age-segregated environments.
  • Exposure to diverse abilities and ideas disrupts “developmentalism”—the flawed assumption that age equals capability.
  • "All wisdom does not have to come from the adults in the room...do kids bring wisdom, don’t they?" (50:30)

10. The Enduring Magic of Nature and Play

• Personal Reflection and Final Thoughts (57:27–58:32)
  • Rusty shares a formative memory: discovering a spring alone in a field, feeling the mystical continuity with the earth and with himself as a child and an adult.
  • "It’s the same spirit that I am now was looking at that...so much more mesmerizing than anything man-made..." (58:22)

• On Risk & Safety:
  "If the goal is for we as adults to feel comfortable when kids are out playing...that’s when you get rubber surfaces and say no all the time..." —Rusty Keeler [37:38]

• On Licensing:
  "Licensing is a good thing...but so many programs feel often limited by what they think licensing will say...the key is being able to use your words to communicate why you have these materials." —Rusty Keeler [44:57]

• On Beauty and Nature:
  "So much more mesmerizing than anything man-made, that nature is the ultimate playground." —Jenny Eric [58:22]
