I found a Slinky and some dominoes at a forest preserve today.
Was it in a little container with GPS coordinates? There are these little things called eco-something-or-others that record how many people pass through an area and what they might have on them. The person, upon stumbling upon the container, writes on a slip of paper who they are and the date. They also right what they are taking out of the container, and what they are leaving. You take something, and you leave something. It's rather interesting.
OT: I found a hole full of hundreds of years old artifacts, but that doesn't really count, since I was on an archaeological dig.
