This cache is a tricky one. Use your geo-sense. You'll find it. Please remember to put everything back the way you found it so others can enjoy it. It's big enough to fit a travel bug or two, as long as they're not attached to anything very big. Bring your own writing stick.
If you come during business hours, you might get some funny looks from behind the glass. Don't worry, though. They are all aware of the cache. I might come out and give you a hard time, though, if I'm bored. :-)
