The cache is not at the above coordinates! The coordinates are fake! Do not go there unless you want seafood or ice cream. Actually maybe go there? But there's no cache there.
In order to retrieve coordinates, complete the You Know What I Miss? Adventure Lab. Along the way you'll find pieces of the coordinates. Put the coordinates together and solve. Geochecker included. The final is located at a historical place in town that was once a particular business, and is now a different one. I can't include history without spoiling it, but take a moment to google it :)
You're looking for a camo-d pill bottle. Please use stealth.
Congrats to KTK57 on FTF both the AL and the bonus :)
