Located in this area was a branch of Atlantic National Bank which served Camp Murphy. ANB was a bank chain based out of Jacksonville, Florida from 1903 to 1985. The bank's vault is still standing and is used by Club Scrub for storage.
On the way to the cache you will pass a concrete foundation and some bricks. The bricks are the remains of a fireplace. Many buildings at Camp Murphy had one: not for heat (this is South Florida after all!), but to burn documents instead of throwing them away. Since the camp involved radar training the army didn't want any classified information to slip out in the garbage.
Also located near here were the headquarters for the 801st Signal Training Regiment and the camp's dispensary.
Watch out for some large spanish bayonet plants in the area. You don't want to get stabbed by one!
