This is reasonably short 2 stage multi. At stage 1 you will find the large forest preserve sign. You will need information here to solve for the stage 2 coordinates. Since I had to change signs, the name doesn't make sense anymore but alas, its really all about the hunt, ammiright?
You are solving for:
N 42° 5.ABC' W 87° 53.XYZ'
A = Lake Ave - East
B = Dam #2
C = Dam #1 - East
X = Walnut Woods
Y = Alison Woods
Z = Dam #1 - West
At stage 2, you are looking for a taped preform container. There is always a way to make a make on the log sheet. Please replace as found.
