You'll need to find the traveling code breaker (TBY8WX) to decipher the code and find the actual GPS coordinates for this cache. Many tricky people have tried to find this cache without the code breaker, but that won't work.
I hope you enjoy the location of the cache. I wasn't aware of the area until recently. I am looking forward to exploring the area more this summer. Its a good place to take geodogs.
