I've been there several times, family comes to visit and want to see the falls. Otherwise you can have your country, pretty unimpressive.
And good Lord, those people cannot freakin' drive! I swear, I was on the Queen Elizabeth Way and I had a guy change lanes and zip between me and a car carrier with a foot to spare on either end of his car. For about half a second, I was sure I was about to die in a fiery end-over-end highway crash, but I remember not being surprised at the prospect, because it was Canada!
