In the world of Harry Potter, The Marauder's Map is a magical parchment showing Hogwarts castle and grounds in its entirety, including seven secret passages into the castle.
When the map is inactive, it appears to be large blank parchment. It is activated by placing a wand on it and saying, "I solemnly swear that I am up to no good." To restore its blank appearance, a wand taps it again as the holder says, "Mischief managed," causing the map to go blank.
Although this cache isn’t quite as magical, it is placed in a busy muggle area, with plenty of unassuming people travelling to work and school, unaware of the magical world of geocaching.
You’ll have to be extra cunning to find this sneaky little cache without getting caught. Let’s hope you’ll be able to say “Mischief Managed” on your way home.
