I want everyone to know I'm not a violent guy, or even really what I'd consider tough, or theatening. But this is what happened:
Once at a 3/d shoot, I leaned my selfbow against a bush to remove my jacket and I had a guy, I didn't even know, just walk up and grab my selfbow. Fortunately, since there's no let off, he got it to a bout 25" and it was too heavy for him. As I took it back from him, I quietly and politely informed him, that when he grabbed my bow, it was the closest he's ever come to feeling a steel toe boot on the side of his face without it actually happening. He started to say something, he stopped myself, and walked back to his buddys. Not exactly ettiquete but he probably won't do it again.
