The other day we drove up the road a bit to see (and hear) the Ringing Rocks.
It's this huge field of boulders, which is somewhat awe inspiring in and of itself.
But the crazy thing is that they ring in different tones when you strike them like bells, or dinner plates, or something else of that sort.
You can see the light colored hollows where many a hammer have gone before us.
We came armed with hammers and wrenches. (FYI hammers work best)
Right before we left, I realized that the pictures would be meaningless without an audio to go with it:
Sadly not the best ring to capture but you get the gist.
