At the bottom of a creek. I doubt it'll still work (looks like it had been there a while) but you may still want it back. If you lost one recently (or a while ago) let me know and I'll get it back to you.
I found it last weekend and stuck it a bag rice to try and dry it out. Just saw it again and realized I'd forgotten to post this. If I can get it charged maybe I can find out who it belongs to.
