At Stage 1:
Locate the establishment's sign a few feet to the west. On it, you will find 3 lines of words, e.g., 2 words, 2 words, 3 words. You will use the number of letters in each word to calculate the Stage 2 coordinates. The number of letters in the 1st word is A, the second word is B, etc., resulting in A thru G.
Coordinates of Stage 2 (about .25 mi away): N 40 09.558+X W 084 18.EFG-644 where:
X = BCD / A
At Stage 2:
Locate the sign just to the west of the driveway. On it, locate the word starting with the letter O and count the number of letters (including the O). This value is H.
Coordinates of the Final Location: N 40 10.249-Y W 084 18.657-Z where:
Y = (EFG - BCD) / H
Z= (EFG - 1) / H
