You can leave a diamond in a happy meal and no one would open it on the side of the street. Useless stuff and geocache.

Random and worse written post for the reason of random & finding what matters to you.

Random items and scavenger hunts, easter eggs and guitar picks.

I once found a guitar pick that looked like a rose petal and it was super badass and it was one of the first things I randomly found that I could say "Maybe this was here specifically so I could find it." It is really cool when we can find a little whatever. We like thrift stores or antique stores. I was with this girl during an art project and we found a really cool bandana cloth or kerchief or neckerchief with skulls and roses.

Make it valuable, or make it cool.

In the small town I am zide in, there is a small cupboard with rocks some girls put up and sometimes I find something cool, sometimes I put something cool there.

It's awesome to have found something random...

I've also found an equation of a child's homework and thought that was interesting.

If they is litter, it might as well be helpful to someone else's story. Why not just buy a random set of guitar picks and put them where someone will find one. It isn't literally if you literally just put it there and leave it.

Random geocache, maybe a dollar somewhere under a statue. There are random things in religious facilities you can often just take but they won't tell you, you are allowed to just take it. Like beads or spices. You can find at times little cuppies of food unperishables and clothing to which I have found stuff because the city often doesn't collect anything. A handsome pencil I can just randomly find, even a pen. Something silly? I've seen rings online for 3 dollars and 25 cents at grocery store quarter machines I used to wear all the time someone would be excited to find. Something else, like a random useless key. Something that can perhaps add to someones story, like a skateboard bearing or a shell, a trinket of some sort, something that makes someone go "Wow, anyone could've picked this up; but it was me!"
