In the caveman days, man learned how to make fire. It probably wasn't too long after that man discovered the need for fire departments.Fire departments are not a catchy, new trend. The earliest fire departments in recorded history date back around 2,000 years to ancient Roman times when men would fight fires by passing buckets of water using a human chain.We're slightly more advanced now, although our method for funding our volunteer fire departments in Warren County is something that's outdated."We're still in the stone age," Harrison Ferry Volunteer Fire Chief Lynn Curtis told me Thursday morning.
