It's a geocaching search.

I had to find 4 geocaches to get the clues for the fifth and final cache.
Initially I had given you the coordinates for one of those first caches.
The second set of coordinates were the CORRECT Clue.
N44.17.946
W088.24.696
I thought that second set would be on the Highway since they gave the hint:
"Do NOT go the above coordinates unless you want to get run over!"
Then 948 feet EAST, and 531 North.
(I am guessing at the North and East part based on the lay and ownership of that tract of land.)
So---according to your diagram, and correcting the numbers to be in accordance with the correct waypoints, the final cache should be about 1/2 inch under the "O" in the word "north" on your second photo?
That is a good possibility since there is a large sign with shrubbery right about that area and would make for a good hiding place.
When I searched yesterday, I was TOO far to the east, and not far enough to the north.
When I go back, I will look in the area that your info gives.
Unfortunately, I live 125 miles from there and won't be able to check it out for a month when I go to visit the folks again!
