This happened to me at one of my baseball games. We were winning by 2 runs and the game was almost over. There were about 20- 30 people In the stands.
I heard a loud noise in the distance, apparently I wasn’t the only one who had heard it. The outfielders came in and told the coach that there was a cougar or something by the fence but it had left. The coaches had no choice but to cancel the game because the umpire told them to.
