The rivers more than any other physical feature demonstrate how nature knows no boundaries. The rivers are the lifeline of civilizations, custodians of cultures, song, music, dance, food, dress and poetry. Rivers are like the eternal guardians of cities, of cultivation and growth, of sustenance and hope, of joys and sorrow, of ebb and flow. The rivers know no boundaries. They are the symbols of progress and travel, the quest for knowledge and they represent the ever present natural channels of man’s eternal voyage.
