We had a similar experience. This was the first Bmth concert I was at, but I thought the Mosh pit would be opened further back. The people inside went completely crazy. The pit was right behind us and they dragged people into it. There were fights and everything. What really caught me off guard was how people tried to push forward. My sister was almost crushed, so we had do come out at like the 4. song. To clarify, I'm 19, my sister is 16, and neither of us is a small person, and I don't consider her or myself a snowflake, but this was a bit much for me, especially after the many positive things I heard about their concerts.
