I think it is appropriate to add this picture (right) to Susan Olsen’s post. The one with the ‘Journalist’s Guide To Firearm’s Identification.’
This is my refrigerator door. It was modified by the manufacturer to accommodate an extra magazine capable of holding all manner of ‘lethal’ ordinance. Soda. Beer. Water, in those earth destroying plastic bottles, paid for with a plastic card, slid through a device made of plastic, carried home in plastic shopping bags and yes…that fridge door modification is made of plastic.
