The conference room at the O.O. Howard House has a capacity of 50 people, but the Clark County Historical Preservation Commission never uses that many chairs. On Tuesday night, the group almost needed a larger room for the first time anyone could remember. The packed crowd was there because the commission was going to discuss the old Jefferson Davis Highway markers, now located at Jefferson Davis Park along Interstate 5 outside of Ridgefield. “Sometimes we get two or three people (at our meetings),” said Robert Hinds, chairman of the commission. “Usually, it’s just us.”Throughout the meeting, the commissioners thanked the crowd for coming out to voice their opinion and take an interest in history, even if there’s not much the commission can do when it comes to the monuments. Since the monuments are on private property, the commissioners can’t take them down. But they can remove the monuments from the official Clark County Heritage Register. They were added to the register in 2002.The board unanimously voted to hold a public hearing on the issue, leading to a round of applause by those in attendance.
