This geocache goes with the Historic Tour of Ypsilanti, Michigan Adventure Lab.
THERE IS NOTHING TO FIND AT THE POSTED COORIDNATES.
Well, except a really cool sign. I would have loved to use it as part of the AL but I ran out of allowable locations.
To solve the puzzle cache and get the final coordinates you must download the adventure lab app and complete the AL titled Historic Tour of Ypsilanti, Michigan. AL's do not have GC codes. So to find this particular AL go to the map in the AL app. Then, go to Ypsilanti, Michigan and click the top bar that says "search this area". The Lab will appear and you can click the green pin to begin the AL. or follow THIS link.
In the lab there are 5 stages. Complete the stages and watch the final page to each location for the cooridantes to use to find the final bonus cache. If you pass the page up before noting the coordinates, no worries. You can go back and see the information in the journal enteries.
Please note! The Adventure Lab caches are done in a seperate app from Geocaching. The app is free and can be downloaded where you get apps for your phone. Learn more here! Also, as of this post you must use a smart phone and an app to do AL's. GPS units will not work.
YOU MUST DO THE ADVENTURE LAB FIRST TO GET THE FINAL COORDS FOR THIS GEOCACHE.
Congratulations to HelloLola for the first to solve on the AL and the FTF on this cache!
