Sometimes when I see an out-of-place gravel in the yard, I wonder if the kids next door threw it over (or if a gravel caught the edge of a car tire and was tossed into the yard). Today, I saw what at first looked like a gray gravel atop the stub of a dead limb I had sawed off. How in the world could they have thrown a gravel over the fence and had it land just so? Aha, it was not a gravel at all; it was a gray tree frog.
Doesn't this look a bit like a gray granite gravel?
