No matter how they categorize them, there will always be two Niagara Falls - the Falls by day and the Falls by night.
Imagine seeing the Falls by night first. Open your senses to the things that only feeling and emotion can appreciate. Save beauty, grandeur and scale for daylight hours. Let them go for now and close your eyes. Breathe. Stretch out with your feelings and lay your hands on the cool metal railing in front of you. It's perfectly safe. Here at the edge of the great Falls, hear the sustained, awesome roaring of the water rushing by, feel the power of its passing shaking the bedrock beneath your feet, see the lights dancing in the mist, and taste the damp freshness of it on your face. All of this and yet there is so much that can't be seen, just felt. Listen closely to your feelings. They once said that the voice of the Great Spirit was in the thunder of the falls. Can you hear it?
