The cache is not at the posted coordinates, but it's a nice park. This is a reverse whereigo cache.
Reverse Wherigo caches can be intimidating, but after you find your first one, you'll discover that they are easy. Once you have the cartridge on your gps or phone, it becomes a virtual version of the "Reverse Cache Box." You will need to enter the key listed below (the 3 numbers) that are unique to each reverse wherigo. Once you have done this you will then be able to run the cartridge which tells you the distance to the cache, but not the bearing. You may begin your search from any spot in the world. You may use this cartridge on any reverse wherigo that uses the same cartridge page created by -Waldmeister.
These are the 3 numbers that you will enter as the "key" so to speak that is unique to each individual reverse wherigo and will not give you coordinates but rather indicate the distance to the final/geocache. Your task is to find the geocache using the box as little as possible for checking the distance.
