The cache IS located at the posted coordinates. However, in order to log this cache as a find, you or your registered team name must have found at least 5 caches with a difficulty rating of 5. Previous finds count. All log entries will be verified through finder's profile. Any "Found" logs that DO NOT qualify will be deleted.
The St. Paul Challenge Series is intended to be a series of challenge caches that is accessible even to casual cachers. You could drive from cache to cache, but most caches are located 0.13 miles apart, so I recommend walking. I have attempted to place the caches in a logical order so that you can get them in numerical order with minimal street crossings. In a few instances, because of unsuitable geo-beacons, I had to put the cache on the opposite side of the street. I hope that you will forgive me.
