To find the cache you must first do a Harry Potter quiz to get the
remaining coordinates. The following are the coordinates you will
need to solve: N 33 17.ABC W 111 40.98D
To solve for A: How many siblings does Harry Potter have?
To solve for B: In what number book does Harry learn he has a
godfather?
To solve for C: In what number book does Professor Slughorn
become the Potions teacher at Hogwarts?
To solve for D: What number Harry Potter book ends the
series?
Once you have solved the questions, fill in the numbers with the
corresponding letters and you will be left with a complete set of
coordinates. Follow the coordinates just like with a regular
cache.
If you wish, use the following to check the coordinates you have
obtained from the quiz to verify you have them correct.
