When Nick and Tessa Groff walk into a room, the line between intuition and evidence gets razor thin. In this episode of the Ghost City Podcast, we explore how a veteran paranormal investigator and a lifelong medium built a partnership where technology and testimony collide in real time. From Nick’s early fascination with Area 51 and filmmaking to Tessa’s near-death experience and psychic abilities she once tried to suppress, their paths converge on a shared philosophy: treat every spirit like a person first. The result is ghost hunting that blends EVP sessions, controlled experimentation, and intuitive insight: cross-checked, replayable, and rooted in respect.

We dig into cases that still echo, including an EVP declaring “Mark is dead” inside a historic theater and a deeply personal reading delivered to a mayor about his late father’s reclaimed accent. The conversation moves beyond spectacle into bigger questions about energy, consciousness, boundaries, and why vulnerability can invite contact. Nick and Tessa also preview their upcoming documentary, The Devil’s Mark, which follows a trauma-aware investigation into attachment and possession without leaning on religious tropes. If you’re interested in paranormal investigation that balances heart, skepticism, and evidence, this episode offers a rare look at what happens when experience, empathy, and equipment all point to the same moment.

In Part 2 of our conversation with Cliff Barackman, curator of the North American Bigfoot Center, we go deeper into what footprints and trackways can actually reveal about Sasquatch behavior. Drawing from decades of field research, Cliff explains why Bigfoot likely doesn’t form human-like “societies,” but instead shows social patterns consistent with known great apes—overlapping home ranges, recurring size classes traveling together, and large males moving along territorial edges. We also tackle a perennial question in cryptozoology: if Bigfoot is real, why don’t trail cameras solve the mystery? The answer lies in ecology and engineering, from limited camera fields of view to high-frequency sounds that wildlife may detect long before a photo is taken.

From there, we dismantle the Bigfoot migration myth by looking at long-term data—repeated tracks from the same individuals across multiple seasons, pointing to stable home ranges rather than continent-spanning movement. Cliff shares practical field strategies that actually work, including targeting corridors near water, understanding seasonal substrates, and methodically expanding search areas over time. We also explore how focused funding and university-linked research could move Bigfoot studies forward, the origins of the North American Bigfoot Center, and why cutting through hoaxes matters more than ever. If you care about reproducible evidence, smart fieldwork, and pushing the conversation beyond noise, this episode delivers.

In Part 1 of this two-part episode of the Ghost City Podcast, Tim Nealon sits down with Cliff Barackman, curator of the North American Bigfoot Center, to approach Sasquatch the way scientists approach any undiscovered species, through evidence, patterns, and repeatable data. Cliff explains why footprints matter more than fleeting sightings and how detailed trackway analysis can reveal behavior like foraging habits, seasonal movement, social grouping, and territory. The long-term patterns he’s documenting, recurring track sizes, repeated visits to the same micro-sites, and consistent seasonal windows, challenge popular Bigfoot migration myths and point instead toward stable home-range behavior.

The conversation moves from the forest floor to the lab, where an interdisciplinary team at North Carolina State University is testing environmental DNA (eDNA) from soil collected inside and outside suspected footprints. While early results don’t “prove Bigfoot,” they do establish a critical, auditable framework, one that allows future genetic discoveries to be cross-checked against archived samples. Along the way, Cliff tackles the cultural baggage surrounding Bigfoot research, separating evidence-based inquiry from paranormal hype, and explains how careful documentation, historical archives, and even limited uses of AI can support serious fieldwork without distorting the data. If you’re interested in Bigfoot research rooted in biology, method, and patience, not myth, this episode lays the groundwork.
