The Queen's Green Canopy

After dropping Ms H up the toon we went a walk around the old oaks path in Dalkeith Country Park, it was very warm and humid. As we were just reaching the end we noticed a plaque for The Queen's Green Canopy which I'd only just heard of yesterday when watching David Attenborough talk to the Queen. Arlo and I walked around this walk a few months ago so it must have been added since then.
