  • Bilgers Rocks - Create your own adventure through a towering rock city
    Jun 24 2026

    What’s the best gift you’ve been given? It’s a tough question. I’ve been fortunate to have received a lot of great gifts over the years. The minibike from my parents. The engraved knife from my brother. The souvenir medal from my wife. And countless others.

    They’re awesome and they each hold a special place in my heart.

    But when I learned of the recent gift that the Commonwealth of Pennsylvania received, it stopped me in my tracks. In 2026, the Pennsylvania Department of Conservation and Natural Resources announced it had been given and has added Bilgers Rocks to the Moshannon State Forest.

    Some of you may be thinking, “Who cares about a bunch of dusty old rocks. That’s not a great gift.” But listen here, you have no idea how amazing this place is. It’s the definition of a hidden gem.

    Bilgers Rocks is centered around a multi-acre rock formation that brings visitors through a stunning rock city. With little in the way of handrails and safety features, you can walk through towering sandstone blocks, crawl in rock rooms, squeeze between ancient boulders and explore carvings from visitors past.

    I was in awe the first time I stood on top of and in between these giant walls of rock. It feels like you’re exploring a prehistoric city. Like you’re Indiana Jones searching for treasure. It’s otherworldly and outstanding. And now, a part of our state forest system.

    So, before we get to the interviews, I want to thank the Bilgers Rocks Association -- for its dedication to preservation, for its steadfast stewardship and for its one-of-a-kind gift.

    Knowing that Bilgers Rocks will be protected for generations of Pennsylvanians to come makes me and many others so happy. Thank you, so much.

    On this episode, I speak with John Hecker, Gary Gilmore and Mariah Dunsmore to the podcast. John is the District Manager of the Moshannon State Forest and Gary and Mariah are with the Bilgers Rocks Association.

  • New to nature? Find free inclusive, guided activities with Centred Outdoors
    Jun 10 2026

    For every Pennsylvanian that grew up stomping through creeks, wandering through the woods and exploring our magnificent forests, there’s many more that are just discovering the outdoors.

    Maybe they grew up in a city. Or they mostly played sports. Or their families didn’t have an outdoor background. But now, they’ve found the beauty and splendor of our wonderful public lands.

    That’s so great to see. New people from different backgrounds finding joy in the outdoors. However, not everyone is automatically comfortable in the outdoors. Maybe they’re afraid of bears or snakes or strangers or getting lost.

    They don’t know where they can learn in a welcoming environment and how to develop community. And they don’t know where to start.

    That’s where Centred Outdoors comes in. Based in Central Pennsylvania, Centered Outdoors invites everyone, of every age, background, or fitness level, to explore and enjoy outdoor recreation destinations throughout Centre and surrounding counties.

    They host various programs and activities that cost nothing to participate in and are always open to the public. Whether you’re brand new or a seasoned hiker, there’s always a place for you at a Centred Outdoors event.

    And their events include everything from guided hikes and yoga to campfire gatherings and art workshops. There really is something for everyone at Centred Outdoors.

    I am always jealous of the people that live in and around Centre County, because they have access to these awesome activities and programs. It’s just a little too far from me here in Cumberland County to go up every weekend. And that’s about how often I wish I could participate in their events.

    But even if you don’t live in Central Pennsylvania, the activities and programs hosted by Centred Outdoors are worth the trip. And the region will definitely keep you busy if you decided to do so.

    On this episode, I speak with Olivia Stas to the podcast. Olivia is the program coordinator for Centred Outdoors.

  • What's killing Pennsylvania's trees and how DCNR’s fighting it
    May 27 2026

    The more time I’ve spent outdoors, the more I’ve learned about the threats our trees face here in Pennsylvania. It seems like every other day I’m finding out about a new disease or invasive plant or insect that’s come to our shores and is devastating our trees.

    It’s sad to see our forests choked by kudzu vines. To see our trees impacted by the emerald ash borer, spongy moth and hemlock woolly adelgid. To see the once mighty American Chestnut tree wiped out by blight.

    And lets not forget about other issues like over foresting, wildfires and climate change. All taking a bite from our forests. One tree at a time.

    We will never have the forests that our ancestors would have seen. Old growth trees are limited to a few areas in the Commonwealth. And development has sliced most of our forests into bite-sized pieces.

    But that doesn’t mean we just give up. No way.

    A dedicated group of scientists and foresters are working to address these issues, protect our forests and stay ahead of the future threats that may try to take even more trees from our landscape.

    They are testing out new methods and processes that could save the trees that we have and, hopefully, prevent more species from being taken from us. But it’s not easy work. They are constantly having to adapt to new threats present in an ever-connected world.

    It’s incredibly important work. Anyone who cares for the outdoors – whether you’re a hunter or a hiker – needs to know about what each of us can do to address these threats on our property and help these scientists protect our forests.

    On this episode, I speak with Rosa Yoo. Rosa is a Forest Health Manager with the Pennsylvania Department of Conservation and Natural Resources’ Bureau of Forestry.
