I've found this in a letterbox near Hartland Tor in good condition given that it's been sat for about 4 years.
It looks as if it didn't make it to the official site of Hartland Tor geocache as that's about 80 metres around the corner.
I've tried contacting the owner but I'm not sure they're still caching. A shame if this is true - maybe someone could nudge them that this is found!
I'll put this in a local geocache and send on its journey.
