Galls, by the way, are formed by a variety of insects (usually wasps), and they do not harm the tree.

Obviously, forgers of ancient documents should learn to make ink the old fashioned way. For their benefit (and for interested SCA types) here’s a must-read account on making a medieval book from scratch; the ink comes from “oak galls and iron sulfate.”

Nearby, there’s a well preserved Victorian farmhouse (although you can tell that maintaining it is a constant struggle):

And last but not least, a lake which I thought did a good job of reflecting the clouds:
