This is my favorite type of cache. This time I also included some of my favorite attributes.
Just to be clear, there are NO red herrings here. Just a straight forward puzzle.
To solve it, there are some things you need to know first...
The cache is NOT at the posted coordinates.
N39 and W75 should be assumed.
You are looking for a set of numbers, not a keyword.
Going to the posted coords may help, but is not at all necessary.
You will need a magnetic tool to retrieve something out of reach.
Good luck, and have fun!

You can validate your puzzle solution with certitude.
Nice job KelseyNJ, and ryan_yacullo! Impressive teamwork for FTF!
