If I had a hammer... I'd hammer out danger. I'd hammer out warning... all over this land. And that's what I did. Climbing over the field of resonant rocks hammering to see which ones were most resonant.
And then hammering some more when we got the hang of it.
Maybe you can't see it, but I'm using a nice floral-print hammer courtesy of Kristen's sister, Emily.
Makes you other rocks seem pretty lame.
