Photo of a Photo

I picked a book off the shelf to reread and found this photo which was being used as a bookmark. I took the photo many years ago during a visit to Niagara Falls. The American falls are on the left, a fragment of the Canadian falls are on the right. The boat is the Maid of the Mist and yes, we did the tourist thing and donned a blue plastic poncho and enjoyed the roar (and spray) of the falls from the boat.
