For HAG9 we placed "How the ?#@*&%! did that get there?" - well we found another interesting object out in the woods. It may be somewhat easy to guess why it's there but it's still a strange thing to see while you're out for a hike in the middle of nowhere.
Hopefully you're not vertically challenged... it may be easy for you to see the cache container, even touch the cache container, but you'll need to have a good reach to retrieve it from it's hidey spot.
