This is a great one, it's like a english dual or something. U both start like 100 feet apart and when someone says go u start walking towards each other. When one person says stop, he gets to take one shot at the other guy. If he hits him, he wins. If he doesn't both have to keep walking and the other guy gets to shoot u whenver he wants

people used to actually do this. It's all about when you feel comfortable you can hit the other guy.
