The Shawshank Redemption is one of my favourite movies so I'll make apologies for my script modifications..
Dear Cacher,
If you’re reading this, you’re thinking about getting out. And if you’ll go as far as H Pond cache, maybe you’re willing to go a little further. You remember the name of the cache, don’t you? I could use a good person who knows how to find things. I’ll keep an eye out for you and the bison tube ready. Remember, hope is a good thing, maybe the best of things, and no good thing ever dies. I will be hoping that this cache finds you, and finds you well.
BYOP and tweezers to extract the log.
Remember - the decision to search for any geocache and the responsibility for your own safety lies with you.
