The cache is not at the posted coordinates. You don't not have to go there either as this reverse Wherigo can be played from anywhere.
For this cache you need a Wherigo enabled GPS device or smartphone with the app. You can download the cartridge The Reverse Cache - beta.
To find the cache location, play the cartridge which will give you a distance only from your location to the cache.
You will need to take a few 'readings' to work out the cache location.
To start you will have to enter the following codes for this Wherigo geocache:
714296
199556
742060
Once you have completed the Wherigo and found the cache you will receive you own personal code in which you can create your own reverse Wherigo cache.
Many thanks to -Waldmeister- who created the reverse cache cartridge.
