That's not the only strange cloud formation we've seen on the approach to Buffalo. We once saw nearby Niagara Falls perfectly reflected in the sky. No one's been able to explain that one to me.
Below another relatively unusual sight these days - a lake freighter. On its way west - to Duluth, Minnesota, perhaps, or lands beyond. We once nearly got mown down in the sailing boat by such a monster that crept up swiftly and silently behind us without so much as a toot of its horn. If we hadn't turned round and seen it, it might have been a sorry end to the story.
