My mom has a photo of me when I was about 3 or 4, wearing a tank commander helmet and surrounded by a bunch of toy guns, including a bazooka. I don't even remember it. It didn't hurt that my dad was recently a Marine at the time. I had all the coolest toys. Dad and I both had battery operated tanks, and we'd build houses with Lincoln Logs, then drive the tanks over them.
The toy gun I really remember was my Johnny Eagle .45 auto. I was about 5 or 6, and it seemed huge. You could load it like a real gun, and the spring-operated ammo went pretty far. I can't help but think that my dad bought me most of them so he could play with them too. When I was 10 I got a Mattel M-16 Marauder and it was loud. I shot it next to mom and dad's bedroom early on a Sunday morning, then handed it to my sister before I went downstairs. She still gives me **** about that! That same Christmas I also got a Crosman 760, but that got treated like a real rifle.
