I saw something similar at the LBJ ride this past weekend. On a particular stretch of straight rode, not too from the start, a Gillespie County Sheriff was monitoring and occasionally pulling over riders who crossed the double yellow line to pass other riders. Hopefully this isn't a trend...although I've seen some really stupid behavior on charity rides that might warrant increased scrutiny of the rules of the road.
