When I was a kid growing up in Alaska we lived about a mile from a lake. The lake was used during or after WWII for practice bombing. They would use 100# fake bombs, filled with sand to bomb floating circle targets. There was a fake/practice bomb dump near the lake, it was covered with vegetation when I was young. I often used to dig up the old bomb crates and break them open. Most of the time the bombs were totally rusted out, but every now and then I found one that was still intact. The steel was only about 1/16th inch thick so it didn't take much to rust a hole in them. I even found a few that had the original sky-blue paint. They had ID little tags on them and two C-shaped hoops/hard points.
I used to drag them home behind my bicycle via a dog leash. My mom went absolutely ape the first time she saw one. I was so proud of my find that I brought it into the kitchen. I can still see her waving her arms over her head screaming, "That's a bomb! Get it out of here! Your going to blow up the house! What have you done! AHHHHHHHHHH!!!...
I remember yelling back trying to explain to her that it was hollow, made of nothing but steel. She was so freaked out that she was almost beyond reason.
Anyway, that one is a bit fatter than the 100#ers that I had as a kid.
