For the longest time of my stay in the US, I waited for an opportunity to visit Niagara Falls. When a friend from Rochester invited me, I gladly jumped at the opportunity. Niagara Falls is accessible (with a valid visa of course) both from the American side, and from the Canadian side. I had to stick to the American side, for the lack of a Canadian visa. I had previously heard everyone tell me how the Canadian view of Niagara was way prettier than then American view. I never understood why.
