KELSO BUILDS SUPER BARGES ...VERY CAREFULLY Kelso didn't jump into this big barge business without know- ing that we could do it as good as the best and better than most. It took hard work and big investments in men and machines to develop a yard capable of building, repairing and servicing barges of any size and description. We built the equipment and the manpower skills the other yards wish they had . . . and we built them as carefully as we build barges. Get a better barge.
