There are many Niagara Falls videos on Youtube and various websites and blogs on the internet but by far the best one I've found so far is the one I've posted below (video taped by forever-video.com).
You'll really get the feel for how powerful and majestic this waterfall is. This particular video shows the Canadian Horseshoe Falls, the American, and Bridal Falls.

No wonder the Falls is visited by millions of tourists every year from countries all over the world. It truly is magnificent. Roger and I are so fortunate to live just a five minute drive away and can take pictures any time we want to.
