The Campbell County Board of Supervisors and School Board will hold a joint meeting tomorrow to discuss the future of the county’s schools.            The boards will consider options regarding the schools’ long-term facilities capital improvement plan that could reach into the next 30 years. For now, officials will need to consider two proposals…One suggests not building but renovating existing facilities instead; the other, recommends consolidating the high schools and middle schools into two each. The meeting is open to the public and will be held at 4pm on Tuesday.
