Solo.
Mark, the farmer, walked up to the woods with me before going on his way to continue walking the dogs.
At the end drilled some holes in the large detached flake of conglomerate, a few more to widen the way lower down, and another in an obstructive rock in the floor. Six were charged, well stemmed and the task was completed from a safe distance in the usual satisfactory manner.
There should be another large pile of rubble to shift on Saturday.
