You are looking for Lock and Lock. It is at the posted coordinates, but in order for you to claim a find you must first have found 100 or more caches in Saginaw County, Michigan. This is a challenge cache where you must meet the requirements before claiming a find. I am fine with you signing the log and then posting the find after you have completed the challenge. Difficulty is based on finding the 100 caches. If you are not sure if you qualify for this challenge, run this checker.
