Wish I had taken a pic of one when I climbed up to the the Ramsey Cascades in the Smoky Mountains last October. Lots of water after three days of rain, and a rainbow in the spray during the afternoon sun, that would have been an awesome background. The only crummy shots I have are of me in front of it holding a big stick of Michigan hickory. Pathetic flashaholic moment.
