It’s not just the Great Lakes. We had to build canals to make those navigable. The excessive network of navigable rivers, and barrier islands that connect Corpus Christi, TX with Baltimore, MD, should make everything east of The Mississippi River blue, and most of the western half of the Continental states are within a couple hundred miles of a naturally navigable river. We may have more naturally navigable rivers than the rest of the world combined.
