With a handful of exceptions, every site that I've hit has produced a terminal from a car battery. It doesn't matter where. Parks, homesteads, ball fields, the woods...if it's my first time there, I'm probably going to find a terminal. Sometimes I find more than one.
The fake 1878 50 DM medallion that I posted about a few months back. I found that at a playfield a few blocks from my home. I've found one reference to these items on a German numismatic site. Not only is it a very unusual item, but I'd think that it's unusual to find something like that under a blackberry bush next to a ball field.
How about the time I got trolled hard at a homestead? Remembering advice that I'd read here, I decided to look for obvious hiding spots for a cache. There was a very large tree about twenty feet from where the house used to be. Sounds promising, right? I found a few iron relics and then got a hit that damned near blew the headphones off my ears. I dug down about a foot and hit rusted iron. Now excited, I began removing more dirt and discovered that this old iron object was square. A box? Almost frantically, I began prying it out and recovered...the door from a cast iron wood stove. Why was that even down there? Who does something like that?
On the corner of a playfield here in town that was the site of a school from the twenties to the fifties, one can find an astonishing amount of vintage car parts down to about a foot; after recovering a cool hubcap and a mirror, and uncovering the ends of some larger parts, we decided to just avoid all the big iron signals in that area. I'm still not sure how they got there. I suppose that they could have come in with fill dirt, but that corner doesn't appear to have ever been filled and is level with the street and surrounding properties, all of which date to the twenties as well. I've got nothing.
I found a shallow .45 ACP bullet in a friend's front yard, maybe fifteen feet from the door. It had rifling marks on it and was more or less horizontal in the dirt, so it had not been shot into the ground from close range. My theory is that it floated in from another part of town with just enough energy left to bury itself down an inch or two. This is obviously a stranger find in some communities than others; unfortunately, here in Bremerton, I was not particularly surprised to find something like this.
