There is no cache at the posted coordinates.
The first cache in this series was fairly straight forward but this will take a little bit more thought. The actual coordinates are an average of several readings. You will find the cache at N 53° 3a.deg W 113° 3j.mqr Have Fun :-)
a = P/B
d = (W-Y)/B
e = C/(B+H)
g = S-O-N-H
j = K-S
m = I-Y-C
q = U/V-B+H
r = F-B
Update October 25/15: I have added a hint, the hint is itself a tiny mystery and will not be figured out the same way the main puzzle is but should definitely give you the help you need.
Please take the time to make sure that you are not being watched by muggles and please replace the cache exactly as you found it. Also please do not provide hints in your logs for this cache....that's my job ;-)
Congrats Kid!! you solved the puzzle without the hint and had time to go to Costa Rica for a week before making the find. Color me impressed!! I'm surprised you still managed FTF! Dad vs Kid III coming soon...
