My expectations weren't big when visiting Niagara Falls. Everything more expensive than necessary, too many people, and waterfalls that are smaller than expected. How wrong I was...
I visited Niagara Falls in early April with spring in the air and the water pouring down on the remnants of winter:
Massive icebergs sitting in the mist underneath the never ending cascades carving them and drawing fascinating patterns on their surface, before they will be gone again as summer gets closer.
