The other day I was sitting at the bar and asked the bartender to make me something special. He decided to mix some Amaretto and Cointreau and made a spectacular cocktail! It was so good, I decided to order another and while I watched him make it, I realized that the primary flavors of the main ingredients both have the same number of letters (when spelled out)!
Not only that but if I divided each of these two words into equal pieces, I was left with six different places! If you take those six different places, in alphabetical order, and determine an appropriate number value for each AB, CD, EF, GH, IJ, and KL you can determine the cache's coordinates using the following formula:
N 3(B) (H-K)(J-E).(L-B)(D-E)(H) W 10(K) (F-A)(E-F).G-I)(J-K)(C-E)
Please be very mindful of muggles :)
