If you have, have had, or know anything about horses, you know it's not uncommon for a horse to throw a shoe. I came across this horseshoe one day that had obviously been lost by its owner.
Then, almost within spitting distance, I noticed this horseshoe hanging in a Honey Locust tree. Now, I know horses throw their shoes, but to throw one into a tree is quite a remarkable feat. :-) If you're not familiar with horseshoe superstition, they're never hung upside down. It's believed hanging a horseshoe upside down causes all the luck to run out.
Just a few yards away from the two horseshoes, I found this. It makes me wonder if this was the unlucky owner of said shoes. Perhaps there's something to the superstition, after all.
