** NOTE ** The Geocache is NOT at the posted coordinates!
This is a Bonus Cache. In order to get the corrected coordinates, you must complete the 'Mighty Mac - A Different Point of View' Adventure Lab. It is based just east of the bridge approach in Mackinaw City. There are five stages in this Adventure Lab. Each stage provides an interesting and different view of the Mackinac Bridge along with a few bridge facts. Three stages are on the St. Ignace side of the Straits and two are on the Mackinaw City side of the Straits.
Once each stage is successfully completed, a message will appear that will provided two letters and two digits (e.g. C=2 & I=5). Take note of those letter/digit combinations. Once all five stages are complete, you will have the ten necessary letters and digits to complete this cache's correct coordinates.
Below is the Key...
Correct Coordinates:
N 45* AB. CDE
W 084* FG. HIJ
You will be seeking a camouflage covered, plastic screw-top jar.
I highly recommend saving the 'Headlands Road' view in the Adventure Lab as your last stop.
