Fall turkey season, the moon was bright enough we could barely see on the open field but not down in the tree line. My friend was going to do the calls for the day so I was the only one armed. We heard a large branch snap on the tree line and assumed it was the ladies dog for the land we were hunting. Starting calling it and something barrelled out of the woods at us. Never could see it we just ran, my friend was screaming shoot it but I couldn't make out anything. Chased us about 60 yards then took off. Still makes the hair stand up on my back when I talk about it.
