Mystery Spot 40 is a structure in a national park. To get this one right you need to specify both the name of the structure and the national park in which the structure is located. Traveler readers who answer correctly will qualify for our monthly prize drawing.
Here are all the clues you should need:
You will get more if you live on the upwind side.
You will get nowhere if you are fool who lives there.
You will get one in trade for your two sawbucks if just one is what you want.
Bonus clue, no extra charge: You will get just one if you ask for less than a double dip.
No cheating! If we catch you engaged in sneakery we will make you write on the whiteboard 100 times: “To calculate the circumference of a circle, simply multiply its diameter by 3.14159265358979323846264338327950288419716939937510.”
