I was out caching and it got away from me in the woods. Fell out of my backpack, I think. When I looked, I couldn't find it.
I wanted to put up a sign in the location I thought I'd lost it, but the park police wouldn't allow it. I thought it was gone forever.
After a couple of weeks, I got an email from someone who'd found it.
How?
I had put my name, phone number, and email address on the splash screen. (The screen that displays just after you start it up.)
If you haven't done it with your own GPS, do it now. It could save you hundreds of dollars.
