Where we lived up CR 52(aka Wolf Creek) our washboards were like that. Smooth in the winter. But then $$$ moved in up the mountain and all of the sudden the road got lots of work done on it. Right now our county rd is washboarded out or as grandpa said, it is all corduroy. But soon they will grade it and Mag Water it. That smooths it out and then everyone goes 60 mph on it. Doc said Mid May I can ride roads!
