We have no idea whether it's open to the public.
We also saw for the first time in our lives, a white barn owl. It launched itself about twenty feet above our heads from its tree-home and did a couple of circuits: long enough for us to get a very clear view. It was as white as milk with wings perhaps two feet from tip to tip. We hung around, waiting for a re-appearance and photo-op, but that was that.
Our adopted cat, Shadow, is settling in and squeeking piteously less. Today Clare has been on the phone to various tradespeople as regards installing a catflap. The quote to locate it in the back door (double-glazed top and bottom panes) came to more than £280 so we're examining alternatives.
The catflap itself, from Homebase, came in at less than a tenner.
