Post tenebras lux (pace Calvin): a rainbow crosses the Niagara River at Niagara Falls after a particularly heavy rain-shower, with the <cite>Maid of the Mist</cite> passing beneath it as she approaches the Canadian Falls. In the background you can see the American Falls. This wasn't the end of the rain for the day, however: less than an hour later I took the boat journey and was drenched on the deck before we were anywhere near the falls (which then dumped even more water over everyone).  (Photo taken with my iPhone because by this point my main camera had died an untimely death. I am pleased to report that it has since been revived by Canon technicians, however.)
