Near GZ you will see a small wall with 3 plaques. In Memoriam and Iraq War are the ones that you will need to observe.
In Memoriam has one date. Change the month to its numeric value, then add the 7 digits of this date together to get X.
Iraq War has two dates. Change both months to their numeric values, then add the 13 digits of these dates together to get Y.
X² + 71 = N and -68 + Y*20 = W
You will find the final @ N38 00.N and W122 17.W - - - Check sum all digits = 58
Please be careful - Palm trees have more teeth than sharks that are just as sharp
