THE POSTED COORDS ARE BOGUS
There is a very important but perhaps not well-known to some figure in the American revolution.
Your task is to find the likeness by VIRTUALLY visiting stage one -N 41° 53.233 W 087° 37.611 )and two -N 39° 56.862 W 075° 08.916 (well, you could go there but a tad far and a street view is available elsewhere).
Then you will know who and what type of object you are looking for.
THEN find/figure out the obvious similar object at a very reasonable distance from the posted cords. This is the "third stage. Then at this third stage 3, GO there!
Standing at stage three (which is the object you deduced) point your compass at 2100 and take 12 or so steps or as many as easily can be done. There you will find the log you must find and sign.
The checker is below for that figue/object/likeness and gives you a "go" if within 10 meters of final.
