You'll find the restored Anglican Church nearby (refer to waypoint 1) and a rather unexpected water-fountain-complex (refer to waypoint 2).
If you didn't visit waypoint 2 before finding the cache, you'll want to visit it after you do... no other water sources near-by!
You're looking for a magnetic nano (black).
You'll need to use your fingers rather than your eyes to locate this one.
Beware of muggles and of prying eyes.
Be stealthy.
Be subtle.
