Welcome to the Manistee County Challenge Trail. In order to claim a find on this cache you must have found at least 200 caches in March (any type caches, any March). Cachers may sign a challenge cache's physical log at any time. However, the challenge cache may be logged as found online only after the log is signed and the challenge tasks have been met and documented. The checker below will tell you if you qualify.
Congratulations to Cosmo411 for the FTF!
