You're looking for a nano container, so please BYOP.
Take your time and be patient with this. Have fun with the hunt! Seeing as this is a higher degree of difficulty, I'll be a little less specific with the hints. I'd like to preserve the difficulty a little bit and dignify your caching abillities.
Please put everything back just how you found it. There's no need to make this one "more difficult" for the next cachers. Besides, I'd like to be able to find it again for maintenance. 
Thanks.
Please be respectful of the surrounding ecosystem, and leave everything as it was when you arrived.
In our Caching Around series we've created hides that span the full spectrum of the Difficulty Rating, including the half-stops. You'll see the listing below, showing the difficulty rating then the Caching Around series number. Click on the number to be taken to that cache page. If you're new to the series, why not start at the 1.0 and work your way up to the 5.0 cache. You'll even be able to complete all the ratings by selecting caches that are in geographical proximity. Happy Caching Around!
