This is a typical bflentje Multicache, short and sweet. Proceed to the listed coordinates to locate the secret coordinates to the final. Use the found coordinates and proceed to find the goods. While it may be possible to brute force the final location of this multicache, I think the odds are miniscule.
Another fun geocache by bflentje.
I have NEVER hidden a cache that required destructive behavior in order to find. Abuse of our park system will be frowned upon.
