Most people forget that the Mississippi River carries alot of product between itself and up to the Minnesota River and the St Croix River. Barges are a daily part of life on the Mississippi. They equally share the water with boaters and fisherman. It just sucks to get caught at a lock for a couple of hours, waiting for a barge to get through. This barge was carrying what looked to be petroleum, but I have also seen barges carrying coal and iron ore from Northern Minnesota. It makes you feel like a kid again when you stare in awe at their size. Being a barge captain has to require a LOT of patience.
