I keep wondering why I don't see more of those older T-Birds on the road
There is an efficient way to put rounds downrange with an automatic machine gun- these people are just capping off as many as they can, they've probably never had the chance to squeeze the trigger on something fully auto before and I bet they are lovin' it. Seeing that tracer bounce around brings back bad memories for me, but I will say that I see nothing wrong with the guy letting the kid shoot. In this day and age, it's what you don't know about that will bring you harm, not that which you're familiar with.
