barge transportation is really the backbone of the american economy, and to mix metaphors, the mississippi river is our super highway, so everything from agricultural exports that feed the world, and that is at no time more critical than now with the russian war on ukraine to the petrochemicals, steel for cars, fertilizers that enable farmers to plant the next round of crops, all of these things depend on barge transportation, and what we're facing right now is the narrowing of that eight-lane super highway to a mountain road. >> so tell us more how the war on ukraine is complicating things because obviously the export of grain from ukraine has obviously slowed down heavily. so we need a lot of these crops that are supposed to come down the mississippi.
