Gorgie City Farm, a community farm in Edinburgh city centre is at risk of closure. http://www.gorgiecityfarm.org.uk/
I recall visiting it ages ago. If you are coming to Edinburgh please consider giving them a visit. It is not far from us and would keep the kids amused for a while. It's a real working farm.
I personally would rather not see it turned into a block of flats.
On a different topic the royal Highland show is in two weeks, 23rd to 26th June. We are full on the Saturday. We have our tickets and will post the best photos from the day on our facebook page.
