Since we have had some good feedback from the former hide (A/C Cachin' #24) we just couldn't let this location go cacheless when the A/C caches are archived. Per the name you may have guessed what you'll encounter at GZ, a holding pen for the emporiums pack-horses until they are rounded up and led back in to wait their turn to get back into the action.
Depending on what time you attempt this find, it may be difficult to grab and return while remaining stealthy. And please do use stealth so this cache will be here for the next cacher. But, it's always fun to people watch at this location, so look around and enjoy!
