The coords should lead you to a playground, and you're in the right
spot if you've become a swinger.
The cache itself is 25m away from this point; but which
direction is up to you!
(Please note that it's not within 25m, it's a circumference,
not an area, you need to search!)
(I think the cache is fairly well hidden, so
please resist the urge to give it away with cute
puns!)
