The cache is not at the listed coordinates. While you can park here, there are closer parking locations. The cache is along one of the numerous Columbia pathways. To find the cache location you will need to solve a puzzle:
1.19998 + 1.94161 = Pi (at least to 5 decimal places). Use 2383.364 to find the cache location which is N39 12.AB7 W076 55.CD6
Check Sum: A+B+C+D =15
I don’t think this puzzle is too hard, but it may be difficult for some.
