People living in Niagara Falls in 1911 woke up in the night feeling something was wrong.
It took a while but they finally realized that it was the lack of noise.
They had all become so used to the roar of the falls that the silence was unusual enough to alert their senses.
Of course at that time nearly all the houses were near the falls.
Amazing pictures! Almost 100 years old. Can you imagine walking on Niagara falls?
