Parking at either location is fine....
Stage #1: Make your way to the posted coords....in front of you is a sign. Count ALL the letters(exclude the Big Z logo as a letter) on the front of the sign, checksum = 11. Take that number and subtract the number of letters in lines 1 & 5, add that number to the North coords. For West take the total number of letters again and subtract the number of letters in line 3, add that to the West coords.
Stage #2: You are looking for +/- coords.
Stage #3: When you get to the coords, look "up" at the "sign". How many "different" letters in the 1st word? For North take this number and multiply by 10, subtract that number from the North coords. For West take that same number and multiply by 29, subtract that number from the West coords.
Stage #4: You are looking for coords to the Final.
Stage #5: Final stage....Good Luck!
