Two views of my local "lake" -- actually the dam for an eighteenth-century water-powered factory, whose buildings can be seen in the background. One was taken on Monday, when it was sunny but quite windy (not nearly as bad as it was higher up, I gather) and there was a good chop on the dam; the other was taken yesterday when the water was as smooth as I've ever seen it.
