There’s a gnarly old oak growing out of a jumbled pile of rocks on the west side of Dynamite Valley. I call it “Treerock.” The boys built a small wooden platform on one of the limbs, but learned the hard way that the base of the tree is encircled with poison oak. It’s the only place on the farm where I’ve found that nasty weed, and, as soon as I find someone immune to it, we’ll eradicate it.
