You may soon notice a couple more boats out on our rivers. Two new towboats were officially christened Tuesday at a ceremony on the North Shore. The Renee Lynn and the Alice Jean were both named after family members of long-time Campbell Transportation Company employees.

Out of sight, out of mind. That pretty well sums up the layperson's view of the country's extensive inland waterways system, an efficient, environmentally friendly network of rivers, locks and canals that moves our huge fleet of floating pack mules, aka barges, powered by towboats.
