The published coordinates will take you to what looks at first sight like a pretty normal suburban property. But wait, animals live here as well as humans. The two dogs will no doubt want to know what you're up to but with a kind word they'll most likely saunter off back to whatever they were doing. Anyway. It's not them you're here to see.
The cache is not at the published coordinates but is a short drive away at
S 41 08. (standing duck) (pig) (bear)
E 173 00. (eagle) (sitting duck) (unicorn)
Check sum: The missing digits add to 28
Don't worry if you feel you're drawing attention to yourself at the zoo. The owners know what you're up to.
Best be a bit stealthy when you're searching for the cache though.
