Someone with a blog called Writeronthestorm’s Weblog has posted about a recent trip to Niagara Falls:
Whilst staying in New York, I booked a hotel at Niagara Falls. I neglected to check which side of the falls the hotel was, US or Canadian. After a brief visit to the Crowne Plaza on the US side, I found myself across the border in the Crowne Plaza on the Canadian side of the falls.
