The rancher across the road from us is doing some fence maintenance. He's taking over the operation of his parent's cattle ranch and the fences haven't been maintained properly for several years. One particular stretch, probably a half mile, is overgrown with hedge trees (osage orange) to the point where you can't even get to the fence posts sufficiently to fix the barbed wire. In my younger days this would just mean breaking out the chainsaw and most of the family members and clearing out trees, one at a time. It takes weeks. Not today (if you have the money).
One day a bulldozer and an excavator show up. In the course of about three days the half mile of osage orange trees has been taken out and stacked for burn. They haven't rebuilt the fence row yet, but the worst is over, and it looks sharp. They've already reworked the fence along the road with nice 5-strand tight barbed wire. He knows how to do it right.
When the tree-clearing was finished the dozer was taken to its next job, but the excavator is still there. Last night was a warm night (for March) and I had some time after supper to walk over and sketch this beast.
