Then one day I heard the grader (a brand new Volvo) come flying down the road at road speed, at about twenty to thirty miles an hour. It went by in a flash, but to my surprise I saw that the blade was down. Then a few minutes later it came back the other way, and then it came by a third time.
The surprising thing is that the road is graded better than usual. And the operator did not drop the blade enough to pull up lots of rocks. I'm wondering if speed grading (or whatever it might be called) is a new or common technique. I'm wondering too what will happen when the blade catches one of the bigger rocks??
