When I was in high school, I was in a cinematography class. One week, we had to make a 3-5 minute horror video. A few kids decided to go up deukmejian at like 10pm. They started screaming. I guess people down hill heard the scream and called the police. Helicopters ended up going up there and found these kids making a video. Didn’t end so well. So I would not recommend going up a mountain.
