While standing on the sidewalk, count the letters in the middle word on the post on the left.
Divide that number by 6.
Subtract that new number from the decimal portion of the posted North Coordinates.
Add that same number to the decimal portion of the posted West Coordinates.
Enter those new coordinates into your GPS.
Do a Goto on your GPS to go to the new coordinates you calculated.
Walk to the final.
Hint: 1983 and 717
Trade fairly...don't just take.
1983, 717, Oynpx.
