I've noticed it could be a smart move to find this cache, as it would score you 2 points towards GC33DDP.
Any one of the caches in the following four pairs would also score points, though travelling between the caches might take a good while! Maybe not the best of ideas. They will help you to solve the puzzle though.
A: Deer Park Cave Lookout : A Ruff Find
B: How I Wish You Were Here : Safe-way Back-way
C: When the West Wind Blows : R U Thirsty - West Warwick
D: WLA Meander #8 : A doctor helicopter
The cache is at:
N 51 12 . (A*B) + (A+C+D)
W 000 37 . (C*D)*(A-B) + (A+A-B)
