Occurred on September 14, 2018 / Yellowstone National Park, USA
Info from Licensor: "Just as my family and I arrived at the thermal pool, we see this guy cross over the barricades and head straight for the water. Everyone around us was yelling for him to get out and to be careful. He did not look up and make eye contact with anyone. At one point, he took his shoes and socks off and attempted to put his feet in the water. He was behind the barricade for about 10 minutes and then walked back up to the main road/parking area. There was a moment where I was definitely nervous, you never know what people’s intentions are."
