I plan on proposing to my girlfriend some time this summer and am thinking Niagara Falls would be the perfect place. I want it to be a surprise, so anything too elaborate might tip her off. Also, I'm thinking the most likely scenaro will have us stopping off there on the way back to the U.S from a vsit to her family. She is from Canada and I the U.S. (why I think this would b a perfect location since it's where the two countres come together).
So we won't be sending the night and likely not getting dinner. So, I'm thinking somewhere outdoors with pretty views (of the falls I am assuming) that hopefully won't be too overrun, crowded with other tourists. I know this last one may make it difficult.
