This cache is located in Waverly Park in Lansing, MI (formerly Waverly Golf Course). There is parking near the corner of Saginaw Rd and Waverly Rd (however, the parking lot may not be cleared in the winter.). The park can also be accessed from the Michigan Avenue Park parking lot on Michigan Ave just east of Waverly Rd (you won't have to go through a hole in the fence from here, but it will be a much longer walk). Please respect any posted park hours.
To find the cache, you just need to solve the puzzle below:

This park has started to become a little more popular, and I saw several people hiking the park while I was there to hide the cache, so you may need to be a little stealthy.
Also, depending on the level of maintenance the park receives this year, you may need to travel through some tall grass. In that case, we would recommend boots, pants and bug spray. If they keep it mowed this year, then the walk to the cache should be pretty easy.
Congrats to goldfinch on being First to Find!
