Here's a lost arrow found story that might be a little hard to believe.
A couple of years ago, I lost a woody behind a target. One year later, at the same shoot, we were looking for my brother's arrow behind the same target, and danged if we didn't find my arrow from the year before. I know it was mine because of the distinctive constrution and fletching and the fact that I write the arrow spine and weight between the fletching on all my arrows.
The amazing thing was that the arrow looked like I had just pulled it from my quiver. Finish hadn't started rotting away and the feathers weren't matted and falling off, but looked as fresh as the day I put them on the arrow.
Actually, wasn't too hard to figure out what happened. Someone likely found my arrow the same weekend, if not the same day I lost it, and deposited it in the club's lost arrow bin. This is a club I only visit once a year for its 3-D shoot. The subsequent year, someone must have pulled it out of the lost arrow bin and shot it, just happening to lose it at the same target I did a year earlier.
It's also possible that the person who found it just held onto it for a year. If so, he didn't shoot it much, because the arrow was still in almost new condition.
Regardless, if my brother hadn't missed that target on year two, we would never have found/known about that arrow.
How's that for coincidence. And no, my brother wasn't playing a trick on me.
