Digit Sum Mystery Cache

The cache is not at the posted coordinates but is less than 1 mile away

I always like puzzles where you are told what you need to do to solve them. To solve this puzzle, simply add the digits in the following numbers:

Latitude (digit sum x 1)
Longitude (digit sum x 3)

Cache is sign only. A special pen is undercover .

Enjoy!

You can validate your puzzle solution with Certitude.
