Lost and Found

So, I'm pretty sure I lost my iPod shuffle when we were camping. If anyone has seen it since we were about to go hiking towards the waterfalls - let me know. On the found side, I have a key on my keyring that I've never before seen in my life. The only explanation I came up with is that maybe someone put it on there so that it could rest with my keys while we frolicked in the Northern part of Minnesota. Let me know.
