K so my girlfriend is coming over from China, and just has a tourist visa for US. So she can't go to Canada. So I hear that Niagra falls is really only worth seeing from the Ontario Canadian side, is this true?. In other words should we bother visiting Niagra falls, even though we can't see the Canadian side. Or should I scrap that and go somewhere else, probably NYC or DC. Wondering what Niagra falls is like just on the US side. Thanks
