I have seen many caches that lately have needed certain things
to access the cache coordinates that only a smart phone can
provide. I figured, why not make a cache using as many as I could
think of?
You must complete this mystery cache with a smartphone (or two)
to get the final coordinates to GZ. Best of luck trying it without
one. Once there, it should be an easy find. I recommend going for
this cache with a friend (might make it easier, especially if
they're a smart phone user as well).
