Puzzle caches make it possible to simultaneously stimulate your mind and your muscles. You can simultaneously have fun and have a feeling of great accomplishment. This cache is a tribute to that simultaneous fun.
There is a dollar coin to help defray the cost to the FTF of the car tires burned up rushing to this.
To find the coordinates for the cache, you need to know that all the following give you nothing:
3a-6b-7c-2d+2e-5f+5g+4h+2j-7k
a-6b+3c-7d+e+6f+9g-2h-2j+7k
4a-2b+6c-7d+9e-5f-7g+5h-j+6k
2a+b+7c+7d+e+3f-6g+3h-9j-2k
9a+2b-4c-3d+5e-4f-g-2h+4j-5k
5a+3b-3c+d+7e+f-4g-6h-3j+6k
The cache is at N44 ab.cde W123 fg.hjk
This should get you three fifths of the way there, after that you are on your own, but it should be obvious. On the other hand, this gives more information than you really need.
