Nothing at the posted coordinates. I checked. Instead of searching there, solve the easy puzzle and paddle on over to the container.
Ready?
Everybody wants this, and it's been that way since the dawn of time.
Find out the atomic weight, in grams, of everyone's desire, and round that number up to the next whole number. Add your number to the posted North coordinates.
Got it?
Next, find the atomic number. Subtract that number from the posted West coordinates.
You should be all set.
You WILL need a boat to get to the container. Please wear your PFD and have fun.
One last thing. You must sign the log. No pictures instead. Thanks for being prepared.
