that's awesome, your house your rules.
Children driving cars their parents gave them have killed more than my 12 year old's shotgun.
Besides, his room provides great crossfire at the top of the stairs and my 16yo can hit em in the back coming up from the basement
You know, 12 - 14 used to be the age that a child became a man.
Now we think of them as children till they are 25.
