That is why I keep a loaded remmington 870 12 ga under bed.
I keep my 870 in the wall rack by my bed with 3 rounds of buckshot in the magazine, right above the S&W .38 spl lying on the night stand.
Just for the record, normally there are no kids in our house. When the grandkids come to visit several times each year all the guns are locked up except when we take a .22 pistol and a .22 rifle out to the back yard for them to shoot under close supervision. Next time they're here I plan to introduce my 11 year old granddaughter to my wife's .410 shotgun using the 2-1/2" shells, but my grandson, who will be 6 by then, is still a little too young to handle anything more than a .22 single shot rifle.
I hope to instill a love and respect for firearms and the shooting sports into them the way I was taught by my grandfather in the 1940s and the way I taught my son and daughter in the '60s and '70s. With all the incredible array of electronic games and toys available today, playing cops and robbers or cowboys and Indians( (oops, make that native Americans) with cap guns and broomstick horses like my generation did in the 1930s and 40s probably seems like something out of ancient history to today's kids. Somehow I don't think that zapping an electronic image of a space monster on a TV screen with a wireless control stick is good training for handling real world bad guys like those 2-legged monsters in CT.
