I keep my guns in safes. The arsenal of freedom goes in the large safe in the closet. The home protection goes in a quick open pistol safe in the bedroom. A little expense for a lot of peace of mind. My dad took care of that by taking me to the range early and often. He got in trouble with Mom the first time, I was only three, but I started shooting competitively when I was 10. I was offered scholarships to shoot in college, but instead was recruited and wrapped up a Naval Academy appointment 9 month early. I stopped shooting competitively after college and traded my competitive rifle in for a GE M61 20mm cannon in my F-14. My life would have been much different without guns.
Well, this happened some time ago when my daughter was a baby. She's now a very responsible 7 year old who has been well-trained in gun safety. I doubt she's the curious type about them, but just in case, they are kept where they could never reach her curious hands.
