At Slammedenuff 20, held in Pigeon Forge and Sevierville, Tennessee, the event faced major disruptions due to crowd chaos, reckless behavior, and safety concerns. On Saturday night, large crowds gathered at Jimmy's Market parking lot, resulting in dangerous activities such as engines revving, tire spinning, and people climbing on cars and gas pumps. The situation escalated into fights, requiring police intervention with riot gear, tear gas, and tasers. This led to the early closure of businesses and police clearing the area for public safety. Due to these disturbances and the associated safety risks, the City of Sevierville announced the cancellation of the event's final day on Sunday. The authorities cited the extensive traffic chaos, reckless driving, and the strain on law enforcement and emergency responders as reasons for the cancellation. The event's future in the area is uncertain, with city officials planning to reassess whether it should continue in the Sevierville Convention Center. The organizers expressed disappointment but indicated refunds for attendees who could not participate due to the cancellation. Overall, Slammedenuff 20 was marred by unruly behavior from a subset of attendees, overshadowing the sanctioned event itself and prompting a firm response from local authorities to maintain safety and peace in the community.
