Mr S - I agree with Matbike. You and Silver need to not personally contact the mother of the idiot. She won't grasp the concept that her little boy did anything wrong for YEARS. She reminds me of the type that's crying on the news about how their sons didn't do nothin wrong - while the police are arresting them for murder of 5 people (happened here in N.O.). But sending in a letter to the editor of the local paper, and any other paper that might circulate in the town is a good idea.
I'm happy to be off some rather narrow roads, but everyone (vehicle drivers) were curteous. I could hear a diesel pickup rumbling behind me for about a mile before it was safe to pass. Even when we signaled that the road was clear, he didn't pass until he got to a passing lane. He didn't cross the double yellow to pass us.
(I really do need to update the sig line...)
