When I was in my teens, I lived on Ft Bliss. Our house was surrounded by desert on three sides. I spent many a day wandering around the desert just looking for stuff as kids are apt to do. I found all kinds of military stuff that soldiers had misplaced while on exercises. Canteen cups, M-1 clips, entrenching tools, cans of c-rats, etc.
The neatest things I found was a Civil War Era bayonet and an old Spanish Conquistador's brass stirrup, the kind that looks like a pointy toed boot. My mother used the stirrup as a flower pot, for years. Both items disappeared with my parents passing. You know how that works.
