There is a tower on the Canadian side that you can go up and look over the Falls and the City.  It was easy enough to get up there (it ain’t cheap), but coming down was a problem.  Let’s just say that customer service is not their strong point, and we ended up standing in a line for half an hour just to be told (and it wasn’t just us) that “oh, that elevator isn’t in use anymore”.  I almost lost it at the guy.  But, the view is wonderful, and we found a cute way of getting some photos that are actually reflections from the windows… so you can see us and the City below.
