Not at the posted coordinates!

To find the location of this bottle preform you must first complete two locations of the corresponding Historic Route 66 adventure lab. To get the entire phrase to enter into certitude, you must visit one of two Adventure locations with duplicate phrases, then a third location near the geocache location. You will receive the first part of the final phrase in the Journal entry for a location coming from the northwest or in the Journal entry for a location coming from the southeast. You will receive the second of two parts of the final phrase in the Journal entry for the location nearest to this geocache.

You can validate your puzzle solution with certitude.
Enjoy!
