The WBs once found a geocache on Topsail Island, North Carolina called the Bling Box of Doom. The large cache container holds a locked inner container and a heavy pillowcase filled with 800(!) assorted keys. One of them fits the cache box.
This two-stage puzzle multi takes its inspiration from the Bling Box of Doom, but goes about it quite differently. The posted coordinates will take you to a small container holding the keys to the final location; you’ll need both keys to give you the final. The keys need not and should not be removed from stage one.
You may wish to double-check the cache attributes in your preparations. It is possible to solve the field puzzle without the right tool, but it would be considerably more difficult. The verifier is for those with web access at stage one (or between stages in the comfort of your home or local coffee shop), and it will confirm your final coordinates.
