What's going on with indoor 3d? I heard of one locally with a 22 yard max. Is this just a way to spend a night shooting? Is the challange the crowd of people? The lighting? The only way I see this verry chalaging is if 14's are in play. Maybe I'm sounding cocky but its 20 yards not 45. If you know its a 22 yard max. Then judging yardage shouldn't be an issue. Someone enlighten me.
