Turning around, this is what we see. A nest of mesquite trees, smoky looking in the middle, about where I want my round pen to go. The rusty barrel at right about represents the edge of our property (the acre in between belongs to the folks living in the house you see there). I'm putting the blueberries along the edge of the barbed wire fence, at right (the bags of stuff and the trash cans are supplies for planting blueberries in alkaline soil).
