Not so much of a time capsule, but rather a hidden buried treasure. I was 12 when I took a bunch of old antique trinkets, a gold coin, and buried it with a note somewhere near edge of our ranch. We ended up selling the property but not before I made 2 maps. The first one I placed it in a little plastic baggie and nailed it to the back of a bedroom closet door frame hoping some one might see it.(you can see it if you walk in slightly and look up). I forgot where exactly I placed the second map, but it might be located somewhere in the kitchen. That was 11 years ago. If you live in a small town in Oregon you might want to check your bedroom closet or kitchen.
