The cache is not at the posted coordinates.
Closed sunset to sunrise. Please bring your own pen.
Add the "convergent" to the posted latitude. Subtract the "parallel" from the posted longitude.
[Edit 4/29/12] Sorry, but I had to change the cache location. Please subtract .002 from latitude and .011 from longitude if you have solved the puzzle before. The cache is now a bison tube.
Congratulations to Chrysalides on FTS, and NeoTrinMorpheus on FTF!
